wcsncpy(3)

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.
