NAME

LIBRARY

SYNOPSIS

12       #include <wchar.h>
13
14       wchar_t *wcsncat(wchar_t dest[restrict .n],
15                        const wchar_t src[restrict .n],
16                        size_t n);
17

DESCRIPTION

19       The  wcsncat()  function  is the wide-character equivalent of the strn‐
20       cat(3) function.  It copies at most n wide characters  from  the  wide-
21       character  string  pointed  to  by src to the end of the wide-character
22       string pointed to by dest, and adds a terminating null  wide  character
23       (L'\0').
24
25       The strings may not overlap.
26
27       The  programmer  must  ensure  that  there  is  room  for  at least wc‐
28       slen(dest)+n+1 wide characters at dest.
29

RETURN VALUE

31       wcsncat() returns dest.
