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 (''), 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 null bytes (''), 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.
