-.Ft char *
-.Fn strcat "char * restrict s" "const char * restrict append"
-.Ft char *
-.Fn strncat "char * restrict s" "const char * restrict append" "size_t count"
-.Sh DESCRIPTION
-The
-.Fn strcat
-and
-.Fn strncat
-functions
-append a copy of the null-terminated string
-.Fa append
-to the end of the null-terminated string
-.Fa s ,
-then add a terminating
-.Ql \e0 .
-The string
-.Fa s
-must have sufficient space to hold the result.
-.Pp
-The
-.Fn strncat
-function
-appends not more than
-.Fa count
-characters from
-.Fa append ,
-and then adds a terminating
-.Ql \e0 .
-.Sh RETURN VALUES
-The
-.Fn strcat
-and
-.Fn strncat
-functions
-return the pointer
-.Fa s .
-.Sh SECURITY CONSIDERATIONS
-The
-.Fn strcat
-function is easily misused in a manner
-which enables malicious users to arbitrarily change
-a running program's functionality through a buffer overflow attack.
-(See
-the FSA.)
-.Pp
-Avoid using
-.Fn strcat .
-Instead, use
-.Fn strncat
-or
-.Fn strlcat
-and ensure that no more characters are copied to the destination buffer
-than it can hold.
-.Pp
-Note that
-.Fn strncat
-can also be problematic.
-It may be a security concern for a string to be truncated at all.
-Since the truncated string will not be as long as the original,
-it may refer to a completely different resource
-and usage of the truncated resource
-could result in very incorrect behavior.
-Example:
-.Bd -literal
-void
-foo(const char *arbitrary_string)
-{
-	char onstack[8];
-
-#if defined(BAD)
-	/*
-	 * This first strcat is bad behavior.  Do not use strcat!
-	 */
-	(void)strcat(onstack, arbitrary_string);	/* BAD! */
-#elif defined(BETTER)
-	/*
-	 * The following two lines demonstrate better use of
-	 * strncat().
-	 */
-	(void)strncat(onstack, arbitrary_string,
-	    sizeof(onstack) - strlen(onstack) - 1);
-#elif defined(BEST)
-	/*
-	 * These lines are even more robust due to testing for
-	 * truncation.
-	 */
-	if (strlen(arbitrary_string) + 1 >
-	    sizeof(onstack) - strlen(onstack))
-		err(1, "onstack would be truncated");
-	(void)strncat(onstack, arbitrary_string,
-	    sizeof(onstack) - strlen(onstack) - 1);

-.In string.h
-.Ft char *
-.Fn stpcpy "char *dst" "const char *src"
-.Ft char *
-.Fn strcpy "char * restrict dst" "const char * restrict src"
-.Ft char *
-.Fn strncpy "char * restrict dst" "const char * restrict src" "size_t len"
-.Sh DESCRIPTION
-The
-.Fn stpcpy
-and
-.Fn strcpy
-functions
-copy the string
-.Fa src
-to
-.Fa dst
-(including the terminating
-.Ql \e0
-character.)
-.Pp
-The
-.Fn strncpy
-function copies at most
-.Fa len
-characters from
-.Fa src
-into
-.Fa dst .
-If
-.Fa src
-is less than
-.Fa len
-characters long,
-the remainder of
-.Fa dst
-is filled with
-.Ql \e0
-characters.
-Otherwise,
-.Fa dst
-is
-.Em not
-terminated.
-.Sh RETURN VALUES
-The
-.Fn strcpy
-and
-.Fn strncpy
-functions
-return
-.Fa dst .
-The
-.Fn stpcpy
-function returns a pointer to the terminating
-.Ql \e0
-character of
-.Fa dst .
-.Sh EXAMPLES
-The following sets
-.Va chararray
-to
-.Dq Li abc\e0\e0\e0 :
-.Bd -literal -offset indent
-char chararray[6];
-
-(void)strncpy(chararray, "abc", sizeof(chararray));
-.Ed
-.Pp
-The following sets
-.Va chararray
-to
-.Dq Li abcdef :
-.Bd -literal -offset indent
-char chararray[6];
-
-(void)strncpy(chararray, "abcdefgh", sizeof(chararray));
-.Ed
-.Pp
-Note that it does
-.Em not
-.Tn NUL
-terminate
-.Va chararray
-because the length of the source string is greater than or equal
-to the length argument.
-.Pp
-The following copies as many characters from
-.Va input
-to
-.Va buf
-as will fit and
-.Tn NUL
-terminates the result.
-Because
-.Fn strncpy
-does
-.Em not
-guarantee to
-.Tn NUL
-terminate the string itself, this must be done explicitly.
-.Bd -literal -offset indent
-char buf[1024];
-
-(void)strncpy(buf, input, sizeof(buf) - 1);
-buf[sizeof(buf) - 1] = '\e0';
-.Ed
-.Pp
-This could be better achieved using
-.Xr strlcpy 3 ,
-as shown in the following example:
-.Pp
-.Dl "(void)strlcpy(buf, input, sizeof(buf));"
-.Pp
-Note that because
-.Xr strlcpy 3
-is not defined in any standards, it should
-only be used when portability is not a concern.
-.Sh SECURITY CONSIDERATIONS
-The
-.Fn strcpy
-function is easily misused in a manner which enables malicious users
-to arbitrarily change a running program's functionality through a
-buffer overflow attack.
-(See
-the FSA
-and
-.Sx EXAMPLES . )

-.Xr memmove 3 ,
-.Xr strlcpy 3
-.Rs
-.%T "The FreeBSD Security Architecture"
-.Re
-(See
-.Pa "/usr/share/doc/{to be decided}" . )
-.Sh STANDARDS
-The
-.Fn strcpy
-and
-.Fn strncpy
-functions
-conform to
-.St -isoC .
-The
-.Fn stpcpy
-function is an MS-DOS and GNUism.
-The
-.Fn stpcpy
-function
-conforms to no standard.
-.Sh HISTORY
-The
-.Fn stpcpy
-function first appeared in
-.Fx 4.4 ,
-coming from 1998-vintage Linux.

-.Dt STRLCPY 3
-.Os
-.Sh NAME
-.Nm strlcpy ,
-.Nm strlcat
-.Nd size-bounded string copying and concatenation
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In string.h
-.Ft size_t
-.Fn strlcpy "char *dst" "const char *src" "size_t size"
-.Ft size_t
-.Fn strlcat "char *dst" "const char *src" "size_t size"
-.Sh DESCRIPTION
-The
-.Fn strlcpy
-and
-.Fn strlcat
-functions copy and concatenate strings respectively.  They are designed
-to be safer, more consistent, and less error prone replacements for
-.Xr strncpy 3
-and
-.Xr strncat 3 .
-Unlike those functions,
-.Fn strlcpy
-and
-.Fn strlcat
-take the full size of the buffer (not just the length) and guarantee to
-NUL-terminate the result (as long as
-.Fa size
-is larger than 0 or, in the case of
-.Fn strlcat ,
-as long as there is at least one byte free in
-.Fa dst ) .
-Note that you should include a byte for the NUL in
-.Fa size .
-Also note that
-.Fn strlcpy
-and
-.Fn strlcat
-only operate on true
-.Dq C
-strings.
-This means that for
-.Fn strlcpy
-.Fa src
-must be NUL-terminated and for
-.Fn strlcat
-both
-.Fa src
-and
-.Fa dst
-must be NUL-terminated.
-.Pp
-The
-.Fn strlcpy
-function copies up to
-.Fa size
-- 1 characters from the NUL-terminated string
-.Fa src
-to
-.Fa dst ,
-NUL-terminating the result.
-.Pp
-The
-.Fn strlcat
-function appends the NUL-terminated string
-.Fa src
-to the end of
-.Fa dst .
-It will append at most
-.Fa size
-- strlen(dst) - 1 bytes, NUL-terminating the result.
-.Sh RETURN VALUES
-The
-.Fn strlcpy
-and
-.Fn strlcat
-functions return the total length of the string they tried to
-create.  For
-.Fn strlcpy
-that means the length of
-.Fa src .
-For
-.Fn strlcat
-that means the initial length of
-.Fa dst
-plus
-the length of
-.Fa src .
-While this may seem somewhat confusing it was done to make
-truncation detection simple.
-.Pp
-Note however, that if
-.Fn strlcat
-traverses
-.Fa size
-characters without finding a NUL, the length of the string is considered
-to be
-.Fa size
-and the destination string will not be NUL-terminated (since there was
-no space for the NUL).
-This keeps
-.Fn strlcat
-from running off the end of a string.
-In practice this should not happen (as it means that either
-.Fa size
-is incorrect or that
-.Fa dst
-is not a proper
-.Dq C
-string).
-The check exists to prevent potential security problems in incorrect code.
-.Sh EXAMPLES
-The following code fragment illustrates the simple case:
-.Bd -literal -offset indent
-char *s, *p, buf[BUFSIZ];
-
-\&...
-
-(void)strlcpy(buf, s, sizeof(buf));
-(void)strlcat(buf, p, sizeof(buf));
-.Ed
-.Pp
-To detect truncation, perhaps while building a pathname, something
-like the following might be used:
-.Bd -literal -offset indent
-char *dir, *file, pname[MAXPATHLEN];
-
-\&...
-
-if (strlcpy(pname, dir, sizeof(pname)) >= sizeof(pname))
-	goto toolong;
-if (strlcat(pname, file, sizeof(pname)) >= sizeof(pname))
-	goto toolong;
-.Ed
-.Pp
-Since we know how many characters we copied the first time, we can
-speed things up a bit by using a copy instead of an append:
-.Bd -literal -offset indent
-char *dir, *file, pname[MAXPATHLEN];
-size_t n;
-
-\&...
-
-n = strlcpy(pname, dir, sizeof(pname));
-if (n >= sizeof(pname))
-	goto toolong;
-if (strlcpy(pname + n, file, sizeof(pname) - n) >= sizeof(pname) - n)
-	goto toolong;
-.Ed
-.Pp
-However, one may question the validity of such optimizations, as they
-defeat the whole purpose of
-.Fn strlcpy
-and
-.Fn strlcat .
-As a matter of fact, the first version of this manual page got it wrong.
-.Sh SEE ALSO

-.Sh DESCRIPTION
-The
-.Fn strmode
-function
-converts a file
-.Fa mode
-(the type and permission information associated with an inode, see
-.Xr stat 2 )
-into a symbolic string which is stored in the location referenced by
-.Fa bp .
-This stored string is eleven characters in length plus a trailing
-.Dv NUL .
-.Pp
-The first character is the inode type, and will be one of the following:
-.Pp
-.Bl -tag -width flag -offset indent -compact
-.It \-
-regular file
-.It b
-block special
-.It c
-character special
-.It d
-directory
-.It l
-symbolic link
-.It p
-fifo
-.It s
-socket
-.It w
-whiteout
-.It ?
-unknown inode type
-.El
-.Pp
-The next nine characters encode three sets of permissions, in three
-characters each.
-The first three characters are the permissions for the owner of the
-file, the second three for the group the file belongs to, and the
-third for the ``other'', or default, set of users.
-.Pp
-Permission checking is done as specifically as possible.
-If read permission is denied to the owner of a file in the first set
-of permissions, the owner of the file will not be able to read the file.
-This is true even if the owner is in the file's group and the group
-permissions allow reading or the ``other'' permissions allow reading.
-.Pp
-If the first character of the three character set is an ``r'', the file is
-readable for that set of users; if a dash ``\-'', it is not readable.
-.Pp
-If the second character of the three character set is a ``w'', the file is
-writable for that set of users; if a dash ``\-'', it is not writable.
-.Pp
-The third character is the first of the following characters that apply:
-.Bl -tag -width xxxx
-.It S
-If the character is part of the owner permissions and the file is not
-executable or the directory is not searchable by the owner, and the
-set-user-id bit is set.
-.It S
-If the character is part of the group permissions and the file is not
-executable or the directory is not searchable by the group, and the
-set-group-id bit is set.
-.It T
-If the character is part of the other permissions and the file is not
-executable or the directory is not searchable by others, and the ``sticky''
-.Pq Dv S_ISVTX
-bit is set.
-.It s
-If the character is part of the owner permissions and the file is
-executable or the directory searchable by the owner, and the set-user-id
-bit is set.
-.It s
-If the character is part of the group permissions and the file is
-executable or the directory searchable by the group, and the set-group-id
-bit is set.
-.It t
-If the character is part of the other permissions and the file is
-executable or the directory searchable by others, and the ``sticky''
-.Pq Dv S_ISVTX
-bit is set.
-.It x
-The file is executable or the directory is searchable.
-.It \-
-None of the above apply.
-.El
-.Pp
-The last character is a plus sign ``+'' if any there are any alternate
-or additional access control methods associated with the inode, otherwise
-it will be a space.

-.Sh SYNOPSIS
-.In string.h
-.Ft char *
-.Fn strsep "char **stringp" "const char *delim"
-.Sh DESCRIPTION
-The
-.Fn strsep
-function locates, in the string referenced by
-.Fa *stringp ,
-the first occurrence of any character in the string
-.Fa delim
-(or the terminating
-.Ql \e0
-character) and replaces it with a
-.Ql \e0 .
-The location of the next character after the delimiter character
-(or NULL, if the end of the string was reached) is stored in
-.Fa *stringp .
-The original value of
-.Fa *stringp
-is returned.
-.Pp
-An
-.Dq empty
-field (i.e., a character in the string
-.Fa delim
-occurs as the first character of
-.Fa *stringp )
-can be detected by comparing the location referenced by the returned pointer
-to
-.Ql \e0 .
-.Pp
-If
-.Fa *stringp
-is initially
-.Dv NULL ,
-.Fn strsep
-returns
-.Dv NULL .
-.Sh EXAMPLES
-The following uses
-.Fn strsep
-to parse a string, containing tokens delimited by white space, into an
-argument vector:
-.Bd -literal -offset indent
-char **ap, *argv[10], *inputstring;
-
-for (ap = argv; (*ap = strsep(&inputstring, " \et")) != NULL;)

-.Sh HISTORY
-The
-.Fn strsep
-function
-is intended as a replacement for the
-.Fn strtok
-function.
-While the
-.Fn strtok
-function should be preferred for portability reasons (it conforms to
-.St -isoC )
-it is unable to handle empty fields, i.e. detect fields delimited by
-two adjacent delimiter characters, or to be used for more than a single
-string at a time.

-.Ft char *
-.Fn strcasestr "const char *big" "const char *little"
-.Ft char *
-.Fn strnstr "const char *big" "const char *little" "size_t len"
-.Sh DESCRIPTION
-The
-.Fn strstr
-function
-locates the first occurrence of the null-terminated string
-.Fa little
-in the null-terminated string
-.Fa big .
-.Pp
-The
-.Fn strcasestr
-function is similar to
-.Fn strstr ,
-but ignores the case of both strings.
-.Pp
-The
-.Fn strnstr
-function
-locates the first occurrence of the null-terminated string
-.Fa little
-in the string
-.Fa big ,
-where not more than
-.Fa len
-characters are searched.
-Characters that appear after a
-.Ql \e0
-character are not searched.
-Since the
-.Fn strnstr
-function is a
-.Fx
-specific API, it should only be used when portability is not a concern.
-.Sh RETURN VALUES
-If
-.Fa little
-is an empty string,
-.Fa big
-is returned;
-if
-.Fa little
-occurs nowhere in
-.Fa big ,
-.Dv NULL
-is returned;
-otherwise a pointer to the first character of the first occurrence of
-.Fa little
-is returned.
-.Sh EXAMPLES
-The following sets the pointer
-.Va ptr
-to the
-.Qq Li Bar Baz
-portion of
-.Va largestring :
-.Bd -literal -offset indent
-const char *largestring = "Foo Bar Baz";
-const char *smallstring = "Bar";
-char *ptr;
-
-ptr = strstr(largestring, smallstring);
-.Ed
-.Pp
-The following sets the pointer
-.Va ptr
-to
-.Dv NULL ,
-because only the first 4 characters of

-.Sh NAME
-.Nm strtok , strtok_r

-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In string.h
-.Ft char *
-.Fn strtok "char *str" "const char *sep"
-.Ft char *
-.Fn strtok_r "char *str" "const char *sep" "char **last"
-.Sh DESCRIPTION
-.Bf -symbolic
-This interface is obsoleted by
-.Xr strsep 3 .
-.Ef
-.Pp
-The
-.Fn strtok
-function
-is used to isolate sequential tokens in a null-terminated string,
-.Fa str .
-These tokens are separated in the string by at least one of the
-characters in
-.Fa sep .
-The first time that
-.Fn strtok
-is called,
-.Fa str
-should be specified; subsequent calls, wishing to obtain further tokens
-from the same string, should pass a null pointer instead.
-The separator string,
-.Fa sep ,
-must be supplied each time, and may change between calls.
-.Pp
-The implementation will behave as if no library function calls
-.Fn strtok .
-.Pp
-The
-.Fn strtok_r
-function is a reentrant version of
-.Fn strtok .
-The context pointer
-.Fa last
-must be provided on each call.
-The
-.Fn strtok_r
-function
-may also be used to nest two parsing loops within one another, as
-long as separate context pointers are used.
-.Pp
-The
-.Fn strtok
-and
-.Fn strtok_r
-functions
-return a pointer to the beginning of each subsequent token in the string,
-after replacing the token itself with a
-.Dv NUL
-character.
-When no more tokens remain, a null pointer is returned.
-.Sh EXAMPLES
-The following uses
-.Fn strtok_r
-to parse two strings using separate contexts:
-.Bd -literal
-char test[80], blah[80];
-char *sep = "\e\e/:;=-";
-char *word, *phrase, *brkt, *brkb;
-
-strcpy(test, "This;is.a:test:of=the/string\e\etokenizer-function.");
-
-for (word = strtok_r(test, sep, &brkt);
-     word;
-     word = strtok_r(NULL, sep, &brkt))
-{
-    strcpy(blah, "blah:blat:blab:blag");
-
-    for (phrase = strtok_r(blah, sep, &brkb);
-         phrase;
-         phrase = strtok_r(NULL, sep, &brkb))
-    {
-        printf("So far we're at %s:%s\en", word, phrase);
-    }

-The System V
-.Fn strtok ,
-if handed a string containing only delimiter characters,
-will not alter the next starting point, so that a call to
-.Fn strtok
-with a different (or empty) delimiter string
-may return a
-.Pf non- Dv NULL
-value.
-Since this implementation always alters the next starting point,
-such a sequence of calls would always return

-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In wchar.h
-.Ft wchar_t *
-.Fn wcstok "wchar_t * restrict str" "const wchar_t * restrict sep" "wchar_t ** restrict last"
-.Sh DESCRIPTION
-The
-.Fn wcstok
-function
-is used to isolate sequential tokens in a null-terminated wide character
-string,
-.Fa str .
-These tokens are separated in the string by at least one of the
-characters in
-.Fa sep .
-The first time that
-.Fn wcstok
-is called,
-.Fa str
-should be specified; subsequent calls, wishing to obtain further tokens
-from the same string, should pass a null pointer instead.
-The separator string,
-.Fa sep ,
-must be supplied each time, and may change between calls.
-The context pointer
-.Fa last
-must be provided on each call.
-.Pp
-The
-.Fn wcstok
-function is the wide character counterpart of the
-.Fn strtok_r
-function.
-.Sh RETURN VALUES
-The
-.Fn wcstok
-function
-returns a pointer to the beginning of each subsequent token in the string,
-after replacing the token itself with a null wide character (L'\e0').
-When no more tokens remain, a null pointer is returned.
-.Sh EXAMPLES
-The following code fragment splits a wide character string on
-.Tn ASCII
-space, tab and newline characters and writes the tokens to
-standard output:
-.Bd -literal -offset indent
-const wchar_t *seps = L" \et\en";
-wchar_t *last, *tok, text[] = L" \enone\ettwo\et\etthree  \en";
-
-for (tok = wcstok(text, seps, &last); tok != NULL;
-    tok = wcstok(NULL, seps, &last))
-	wprintf(L"%ls\en", tok);
-.Ed
-.Sh COMPATIBILITY
-Some early implementations of
-.Fn wcstok
-omit the
-context pointer argument,
-.Fa last ,
-and maintain state across calls in a static variable like
-.Fn strtok
-does.

-.Xr strtok 3 ,

-.Xr wcscspn 3 ,
-.Xr wcspbrk 3 ,
-.Xr wcsrchr 3 ,
