WCSTOK(3) BSD Library Functions Manual WCSTOK(3)
NAME
wcstok -- split wide-character string into tokens
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <wchar.h>
wchar_t *
wcstok(wchar_t *restrict ws1, const wchar_t *restrict ws2, wchar_t **restrict ptr);
DESCRIPTION
The wcstok() function is used to isolate sequential tokens in a null-terminated wide character string, ws1. These tokens are separated in
the string by at least one of the characters in ws2. The first time that wcstok() is called, ws1 should be specified; subsequent calls,
wishing to obtain further tokens from the same string, should pass a null pointer instead. The separator string, ws2, must be supplied each
time, and may change between calls. The context pointer, ptr, must be provided on each call.
The wcstok() function is the wide character counterpart of the strtok_r() function.
RETURN VALUES
The 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'
