STPNCPY(3)                                          Linux Programmer's Manual                                         STPNCPY(3)



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

SYNOPSIS
       #define _GNU_SOURCE
       #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 '\0'
       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 '\0' characters.  If the length
       strlen(src) is greater or equal to n, the string pointed to by dest will not be '\0' 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.
