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 remaining 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.
