wmemchr - find a wide-character in memory


#include <wchar.h>

wchar_t *wmemchr(const wchar_t *ws, wchar_t wc, size_t n);


The wmemchr() function locates the first occurrence of wc in the initial n wide-characters of the object pointed to be ws. This function is not affected by locale and all wchar_t values are treated identically. The null wide-character and wchar_t values not corresponding to valid characters are not treated specially.

If n is zero, ws must be a valid pointer and the function behaves as if no valid occurrence of wc is found.


The wmemchr() function returns a pointer to the located wide-character, or a null pointer if the wide-character does not occur in the object.


No errors are defined.
