NAME
       stpncpy - copy a fixed-size string, returning a pointer to its end

SYNOPSIS
       #define _GNU_SOURCE
       #include <string.h>

       char *stpncpy(char *dest, const char *src, size_t n);

DESCRIPTION
       The  stpncpy  function  copies  at  most	 n characters from the string
       pointed to by src, including the terminating ’\0’  character,  to  the
       array pointed to by dest. Exactly n characters are written at dest. If
       the length strlen(src) is smaller than n, the remaining characters  in
       the  array  pointed to by dest are filled with ’\0’ characters. If the
       length strlen(src) is greater or equal to n, the string pointed to  by
       dest will not be ’\0’ terminated.

       The strings may not overlap.

       The  programmer	must ensure that there is room for at least n charac-
       ters at dest.

RETURN VALUE
       stpncpy returns a pointer to the terminating null in dest, or, if dest
       is not null-terminated, dest + n.

CONFORMING TO
       This function is a GNU extension.
