       This  manual  page  is part of the POSIX Programmer's Manual.  The Linux implementation of
       this interface may differ (consult the corresponding Linux  manual  page  for  details  of
       Linux behavior), or the interface may not be implemented on Linux.

NAME

       wcscat — concatenate two wide-character strings

SYNOPSIS

       #include <wchar.h>

       wchar_t *wcscat(wchar_t *restrict ws1, const wchar_t *restrict ws2);

DESCRIPTION

       The functionality described on this reference page is aligned with the ISO C standard. Any
       conflict between the requirements described here and the ISO C standard is  unintentional.
       This volume of POSIX.1‐2017 defers to the ISO C standard.

       The  wcscat()  function shall append a copy of the wide-character string pointed to by ws2
       (including the terminating null wide-character code) to  the  end  of  the  wide-character
       string pointed to by ws1.  The initial wide-character code of ws2 shall overwrite the null
       wide-character code at the end of ws1.   If  copying  takes  place  between  objects  that
       overlap, the behavior is undefined.

RETURN VALUE

       The wcscat() function shall return ws1; no return value is reserved to indicate an error.

ERRORS

       No errors are defined.
