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 '' 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 '' characters.  If the length strlen(src) is greater or equal to n, the string pointed to
       by dest will not be '' 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 in dest, or, if dest is not null-terminated, dest + n.

CONFORMING TO
       This function is a GNU extension.
