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 <&lt;string.h>&gt;

       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.
