17 wchar_t *wmemset(wchar_t *ws, wchar_t wc, size_t n);

20 The functionality described on this reference page is aligned with the
21 ISO C standard. Any conflict between the requirements described here
22 and the ISO C standard is unintentional. This volume of POSIX.1‐2017
23 defers to the ISO C standard.
24
25 The wmemset() function shall copy the value of wc into each of the
26 first n wide characters of the object pointed to by ws. This function
27 shall not be affected by locale and all wchar_t values shall be treated
28 identically. The null wide character and wchar_t values not correspond‐
29 ing to valid characters shall not be treated specially.
30
31 If n is zero, the application shall ensure that ws is a valid pointer,
32 and the function shall copy zero wide characters.
33
35 The wmemset() functions shall return the value of ws.
