** 	LIBRARY: <string.h>
** 	SYNOPSIS: size-bounded string copying and concatenation
**
** 	DESCRIPTION:
** 	The strlcpy() and strlcat() functions copy and concatenate strings with the
**	same input parameters and output result as snprintf(3). They are designed to
**	be safer, more consistent, and less error prone replacements for the easily
**	misused functions strncpy(3) and strncat(3).
