NAME
wcstok - split wide-character string into tokens
SYNOPSIS
#include <wchar.h>
wchar_t *wcstok(wchar_t *wcs, const wchar_t *delim, wchar_t **ptr);
DESCRIPTION
The wcstok() function is the wide-character equivalent of the strtok(3)
function, with an added argument to make it multithread-safe. It can
be used to split a wide-character string wcs into tokens, where a token
is defined as a substring not containing any wide-characters from de‐
lim.
The search starts at wcs, if wcs is not NULL, or at *ptr, if wcs is
NULL. First, any delimiter wide-characters are skipped, that is, the
pointer is advanced beyond any wide-characters which occur in delim.
If the end of the wide-character string is now reached, wcstok() re‐
turns NULL, to indicate that no tokens were found, and stores an appro‐
priate value in *ptr, so that subsequent calls to wcstok() will con‐
tinue to return NULL. Otherwise, the wcstok() function recognizes the
beginning of a token and returns a pointer to it, but before doing
that, it zero-terminates the token by replacing the next wide-character
which occurs in delim with a null wide character (L'\0'), and it up‐
dates *ptr so that subsequent calls will continue searching after the
end of recognized token.
RETURN VALUE
The wcstok() function returns a pointer to the next token, or NULL if
no further token was found.

NOTES
The original wcs wide-character string is destructively modified during
the operation.
EXAMPLE
The following code loops over the tokens contained in a wide-character
string.
wchar_t *wcs = ...;
wchar_t *token;
wchar_t *state;
for (token = wcstok(wcs, " \t\n", &state);
token != NULL;
token = wcstok(NULL, " \t\n", &state)) {
...
}
