NAME         top

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

SYNOPSIS         top

       #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)):

           Since glibc 2.10:

DESCRIPTION         top

       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 than 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         top

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