wmemset - set wide characters in memory
wchar_t *wmemset(wchar_t *ws, wchar_t wc, size_t n);
[CX] 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 IEEE Std 1003.1-2001 defers to the ISO C standard.
The wmemset() function shall copy the value of wc into each of the first n wide characters of the object pointed to by ws. 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 ws is a valid pointer, and the function shall copy zero wide characters.
The wmemset() functions shall return the value of ws.
No errors are defined.
