FUNCTION
<<stpncpy>>---counted copy string returning a pointer to its end
INDEX
stpncpy
ANSI_SYNOPSIS
#include <string.h>

TRAD_SYNOPSIS
#include <string.h>
char *stpncpy(<[dst]>, <[src]>, <[length]>)
char *<[dst]>;
char *<[src]>;
size_t <[length]>;
DESCRIPTION
<<stpncpy>> copies not more than <[length]> characters from the
the string pointed to by <[src]> (including the terminating
null character) to the array pointed to by <[dst]>. If the
string pointed to by <[src]> is shorter than <[length]>
characters, null characters are appended to the destination
array until a total of <[length]> characters have been
written.
RETURNS
This function returns a pointer to the end of the destination string,
thus pointing to the trailing '\0', or, if the destination string is
not null-terminated, pointing to dst + n.
