NAME

       wcsncpy - copy a fixed-size string of wide characters

SYNOPSIS

       #include <wchar.h>

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

DESCRIPTION

       The  wcsncpy()  function  is the wide-character equivalent of the strncpy(3) function.  It
       copies at most n wide characters  from  the  wide-character  string  pointed  to  by  src,
       including  the  terminating  null wide character (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 null wide
       characters.  If the length wcslen(src) is greater than or equal to n, the  string  pointed
       to by dest will not be terminated by a null wide character.

       The strings may not overlap.

       The programmer must ensure that there is room for at least n wide characters at dest.

RETURN VALUE

       wcsncpy() returns dest.
