Function Documentation

snd_strlcat()

size_t snd_strlcat	(	char *	dst,
		const char *	src,
		size_t	size )

Append a C-string into a sized buffer.

Parameters

dst	Where to append the string to
src	Where to copy the string from
size	Size of destination buffer

Return values

The	total string length (no trimming)

The result is always a valid NUL-terminated string that fits in the buffer (unless, of course, the buffer size is zero). It does not pad out the result.

snd_strlcpy()

size_t snd_strlcpy	(	char *	dst,
		const char *	src,
		size_t	size )

Copy a C-string into a sized buffer.

Parameters

dst	Where to copy the string to
src	Where to copy the string from
size	Size of destination buffer

Return values

The	source string length

The result is always a valid NUL-terminated string that fits in the buffer (unless, of course, the buffer size is zero). It does not pad out the result like strncpy() does.
