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

SYNOPSIS
       #include <string.h>

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

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       stpncpy():
	   Since glibc 2.10:
	       _XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
	   Before glibc 2.10:
	       _GNU_SOURCE

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

       The strings may not overlap.

       The programmer must ensure that there is room for at least n characters at dest.

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

CONFORMING TO
       This function was added to POSIX.1-2008.  Before that, it was a GNU extension.
