strlcat()

size_t strlcat	(	char *	dst,
		const char *	src,
		size_t	dsize
	)

Safe version of strncat() from OpenBSD.

Parameters

dst	Destination string
src	Source string
dsize	Total maximum size of dst

Appends src to string dst of size dsize (unlike strncat(), dsize is the full size of dst, not space left). At most dsize-1 characters will be copied. Always NUL terminates (unless dsize <= strlen(dst)).

Returns

strlen(src) + MIN(dsize, strlen(initial dst)). If retval >= dsize, truncation occurred.
