wmemcpy_s(3c)

wmemcpy(3C)              Standard C Library Functions              wmemcpy(3C)

NAME
       wmemcpy, wmemcpy_s - copy wide-characters in memory

SYNOPSIS
       #include <wchar.h>

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


       #define __STDC_WANT_LIB_EXT1__ 1
       #include <wchar.h>

       errno_t wmemcpy_s(wchar_t *restrict ws1, rsize_t ws1max,
           const wchar_t *restrict ws2, rsize_t n);

DESCRIPTION
       The wmemcpy() function copies n wide-characters from the object pointed
       to  by  ws2  to  the object pointed to be ws1. This function is not af‐
       fected by locale and all wchar_t values are  treated  identically.  The
       null wide-character and wchar_t values not corresponding to valid char‐
       acters are not treated specially.


       If n is zero, ws1 and ws2 must both be valid pointers, and the function
       copies zero wide-characters.


       The  wmemcpy_s() function is part of the C11 bounds checking interfaces
       specified in the C11 standard, Annex K. It provides similar functional‐
       ity to the wmemcpy() function, except for additional checks on the  pa‐
       rameters  passed and explicit runtime constraints as defined in the C11
       standard.   See   runtime_constraint_handler(3C)   and   INCITS/ISO/IEC
       9899:2011.

RETURN VALUES
       The wmemcpy() function returns the value of ws1.


       If  no  runtime constraint violation is detected, the wmemcpy_s() func‐
       tion returns 0, otherwise, it returns a non-zero value.

ERRORS
       No errors are defined.

   MT-Level
       The wmemcpy() function is Async-Signal-Safe.


       The wmemcpy_s() function cannot be used safely in a  multithreaded  ap‐
       plication  due to the runtime constraint handler. For more information,
       see the runtime_constraint_handler(3C) man page.

   Standard
       See standards(7) for descriptions of the following standards:
