Collaboration diagram for Non-standard functions:

Functions
void	lwip_itoa (char *result, size_t bufsize, int number)

int	lwip_stricmp (const char str1, const char str2)

int	lwip_strnicmp (const char str1, const char str2, size_t len)

char *	lwip_strnstr (const char buffer, const char token, size_t n)

Detailed Description

lwIP provides default implementations for non-standard functions. These can be mapped to OS functions to reduce code footprint if desired. All defines related to this section must not be placed in lwipopts.h, but in arch/cc.h! These options cannot be #defined in lwipopts.h since they are not options of lwIP itself, but options of the lwIP port to your system.

Function Documentation

◆ lwip_itoa()

void lwip_itoa	(	char *	result,
		size_t	bufsize,
		int	number
	)

lwIP default implementation for itoa() non-standard function. This can be #defined to itoa() or snprintf(result, bufsize, "%d", number) depending on your platform port.

Definition at line 196 of file def.c.

◆ lwip_stricmp()

int lwip_stricmp	(	const char *	str1,
		const char *	str2
	)

lwIP default implementation for stricmp() non-standard function. This can be #defined to stricmp() depending on your platform port.

Definition at line 126 of file def.c.

◆ lwip_strnicmp()

int lwip_strnicmp	(	const char *	str1,
		const char *	str2,
		size_t	len
	)

lwIP default implementation for strnicmp() non-standard function. This can be #defined to strnicmp() depending on your platform port.

Definition at line 161 of file def.c.

References pbuf::len.

◆ lwip_strnstr()

char* lwip_strnstr	(	const char *	buffer,
		const char *	token,
		size_t	n
	)

lwIP default implementation for strnstr() non-standard function. This can be #defined to strnstr() depending on your platform port.

Definition at line 103 of file def.c.
