Detailed Description

Safe version of strncat() and strncpy() taken from the BSD stdlib.

Function Documentation

◆ xstrlcat()

size_t xstrlcat	(	char *	dst,
		const char *	src,
		size_t	siz
	)

Safe string concatenation.

Appends src to string dst of size siz (unlike strncat, siz is the full size of dst, not space left). At most siz-1 characters will be copied. Always NUL terminates (unless siz <= strlen(dst)). Returns strlen(src) + MIN(siz, strlen(initial dst)). If retval >= siz, truncation occurred.

Taken from BSD library.

Parameters

dst	Destination buffer
src	Source buffer
siz	Max size of destination buffer including terminating NULL

Returns: The number of bytes needed to be copied. If this is > siz then data truncation happened.

◆ xstrlcpy()

size_t xstrlcpy	(	char *__restrict	dst,
		const char *__restrict	src,
		size_t	dsize
	)

Safe string copy.

Copy string src to buffer dst of size dsize. At most dsize-1 chars will be copied. Always NUL terminates (unless dsize == 0). Returns strlen(src); if retval >= dsize, truncation occurred.
