+.Dd October 3, 2002
+.Dt WCSTOK 3
+.Os
+.Sh NAME
+.Nm wcstok
+.Nd split wide-character string into tokens
+.Sh LIBRARY
+.Lb libc
+.Sh SYNOPSIS
+.In wchar.h
+.Ft wchar_t *
+.Fn wcstok "wchar_t * restrict str" "const wchar_t * restrict sep" "wchar_t ** restrict last"
+.Sh DESCRIPTION
+The
+.Fn wcstok
+function
+is used to isolate sequential tokens in a null-terminated wide character
+string,
+.Fa str .
+These tokens are separated in the string by at least one of the
+characters in
+.Fa sep .
+The first time that
+.Fn wcstok
+is called,
+.Fa str
+should be specified; subsequent calls, wishing to obtain further tokens
+from the same string, should pass a null pointer instead.
+The separator string,
+.Fa sep ,
+must be supplied each time, and may change between calls.
+The context pointer
+.Fa last
+must be provided on each call.
+.Pp
+The
+.Fn wcstok
+function is the wide character counterpart of the
+.Fn strtok_r
+function.
+.Sh RETURN VALUES
+The
+.Fn wcstok
+function
+returns a pointer to the beginning of each subsequent token in the string,
+after replacing the token itself with a null wide character (L'\e0').
+When no more tokens remain, a null pointer is returned.
+.Sh EXAMPLES
+The following code fragment splits a wide character string on
+.Tn ASCII
+space, tab and newline characters and writes the tokens to
+standard output:
+.Bd -literal -offset indent
+const wchar_t *seps = L" \et\en";
+wchar_t *last, *tok, text[] = L" \enone\ettwo\et\etthree  \en";
+
+for (tok = wcstok(text, seps, &last); tok != NULL;
+    tok = wcstok(NULL, seps, &last))
+        wprintf(L"%ls\en", tok);
+.Ed
+.Sh COMPATIBILITY
+Some early implementations of
+.Fn wcstok
+omit the
+context pointer argument,
+.Fa last ,
+and maintain state across calls in a static variable like
+.Fn strtok
+does.
+.Sh SEE ALSO
+.Xr strtok 3 ,
+.Xr wcschr 3 ,
+.Xr wcscspn 3 ,
+.Xr wcspbrk 3 ,
+.Xr wcsrchr 3 ,
+.Xr wcsspn 3
+.Sh STANDARDS
+The
+.Fn wcstok
+function
+conforms to
+.St -isoC-99 .
