** LIBRARY: <string.h>
** SYNOPSIS: save a copy of a string (with malloc)
**
** DESCRIPTION:
** 		The strdup() function allocates sufficient memory for a copy of the
**	string s1, does the copy, and returns a pointer to it.  The pointer may
**	subsequently be used as an argument to the function free(3).
