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



NAME
       wcpncpy  -  copy  a  fixed-size  string of wide characters, returning a
       pointer to its end

SYNOPSIS
       #define _GNU_SOURCE
       #include <&lt;wchar.h>&gt;

       wchar_t *wcpncpy(wchar_t *dest, const wchar_t *src, size_t n);

DESCRIPTION
       The wcpncpy() function is the wide-character  equivalent  of  the  stp-
       ncpy(3)  function.   It copies at most n wide characters from the wide-
       character string pointed to by src,  including  the  terminating  L'\0'
       character,  to the array pointed to by dest.  Exactly n wide characters
       are written at dest.  If the length wcslen(src) is smaller than n,  the
       remaining  wide  characters  in the array pointed to by dest are filled
       with L'\0' characters.  If the length wcslen(src) is greater  or  equal
       to n, the string pointed to by dest will not be L'\0' terminated.

       The strings may not overlap.

       The programmer must ensure that there is room for at least n wide char-
       acters at dest.

RETURN VALUE
       wcpncpy() returns a pointer to the last wide  character  written,  that
       is, dest + n - 1.

CONFORMING TO
       This function is a GNU extension.
