The
wcstok() function is used to isolate sequential tokens in a nul-terminated wide character string,
str. These tokens are separated in the string by at least one of the characters in
sep. The first time that
wcstok() is called,
str should be specified; subsequent calls, wishing to obtain further tokens from the same string, should pass a null pointer instead. The separator string,
sep, must be supplied each time, and may change between calls. The context pointer
last must be provided on each call.
The
wcstok() function is the wide character counterpart of the
strtok_r() function.
