Here is the call graph for this function:

◆ fdestroy()

int fdestroy	(	struct thread *	td,
		struct file *	fp,
		int	fd
	)

This destroys a thread local file descriptor.

This function will destroy the thread local file file specified as fd, for sanity it requires the file descriptor id and memory address to check before destroying.

Note: This text shall only show you, how such a "note" section is looking. There is nothing which really needs your notice, so you do not really need to read this section.

Parameters

td	Pointer to thread which initiated the syscall.
fp	Pointer to the thread local file which you want to destroy.
fd	File descriptor id that points to the thread local file which you want to destroy.
