NAME

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

SYNOPSIS

       #include <wchar.h>

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

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       wcpncpy():
           Since glibc 2.10:
               _XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
           Before glibc 2.10:
               _GNU_SOURCE

DESCRIPTION

       The  wcpncpy()  function  is the wide-character equivalent of the stpncpy(3) function.  It
       copies at most n wide characters  from  the  wide-character  string  pointed  to  by  src,
       including  the  terminating null wide (L'\0'), 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 characters at dest.

RETURN VALUE

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

CONFORMING TO

       POSIX.1-2008.
