       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

       wmemcpy — copy wide characters in memory

SYNOPSIS

       #include <wchar.h>

       wchar_t *wmemcpy(wchar_t *restrict ws1, const wchar_t *restrict ws2,
           size_t n);

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  wmemcpy()  function shall copy n wide characters from the object pointed to by ws2 to
       the object pointed to by ws1.  This function shall not  be  affected  by  locale  and  all
       wchar_t  values  shall  be treated identically. The null wide character and wchar_t values
       not corresponding to valid characters shall not be treated specially.

       If n is zero, the application shall ensure that ws1 and ws2 are valid  pointers,  and  the
       function shall copy zero wide characters.

RETURN VALUE

       The wmemcpy() function shall return the value of ws1.
