27 Parse S into tokens separated by characters in DELIM.
28 If S is NULL, the saved pointer in SAVE_PTR is used as
29 the next starting point. For example:
30 char s[] = "-abc-=-def";
32 x = strtok_r(s, "-", &sp); /* x = "abc", sp = "=-def" */
33 x = strtok_r(NULL, "-=", &sp); /* x = "def", sp = NULL */
34 x = strtok_r(NULL, "=", &sp); /* x = NULL */
35 /* s = "abc\0-def\0" */
37 char *strtok_r (char *s, const char *delim, char **save_ptr)
44 /* Scan leading delimiters. */
45 s += strspn (s, delim);
52 /* Find the end of the token. */
54 s = strpbrk (token, delim);
56 /* This token finishes the string. */
57 *save_ptr = __rawmemchr (token, '\0');
60 /* Terminate the token and make *SAVE_PTR point past it. */
