wcstok(3) Library Functions Manual wcstok(3) wcstok - () LIBRARY Standard C library (libc, -lc) #include wchar_t *wcstok(wchar_t *restrict wcs, const wchar_t *restrict delim, wchar_t **restrict ptr); wcstok() strtok(3) , . wcs , , delim. 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() returns NULL, to indicate that no tokens were found, and stores an appropriate value in *ptr, so that subsequent calls to wcstok() will continue 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 updates *ptr so that subsequent calls will continue searching after the end of recognized token. wcstok() NULL, . attributes(7). +----------------------------+----------------------------------------------------------+--------------------------+ | | | | +----------------------------+----------------------------------------------------------+--------------------------+ |wcstok() | | MT-Safe | +----------------------------+----------------------------------------------------------+--------------------------+ C11, POSIX.1-2008.
