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);

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.
