Life isn't about finding yourself, life is about creating yourself.

```
#include <string.h>

char *
_DEFUN (__strtok_r, (s, delim, lasts, skip_leading_delim),
	register char *s _AND
	register const char *delim _AND
	char **lasts _AND
	int skip_leading_delim)
{
	register char *spanp;
	register int c, sc;
	char *tok;

if (s == NULL && (s = *lasts) == NULL)
		return (NULL);

/*
	 * Skip (span) leading delimiters (s += strspn(s, delim), sort of).
	 */
cont:
	c = *s++;
	for (spanp = (char *)delim; (sc = *spanp++) != 0;) {
		if (c == sc) {
			if (skip_leading_delim) {
				goto cont;
			}
			else {
				*lasts = s;
				s[-1] = 0;
				return (s - 1);
			}
		}
	}

if (c == 0) {		/* no non-delimiter characters */
		*lasts = NULL;
		return (NULL);
	}
	tok = s - 1;

/*
	 * Scan token (scan for delimiters: s += strcspn(s, delim), sort of).
	 * Note that delim must have one NUL; we stop if we see that, too.
	 */
	for (;;) {
		c = *s++;
		spanp = (char *)delim;
		do {
			if ((sc = *spanp++) == c) {
				if (c == 0)
					s = NULL;
				else
					s[-1] = 0;
				*lasts = s;
				return (tok);
			}
		} while (sc != 0);
	}
	/* NOTREACHED */
}

char *
_DEFUN (strtok_r, (s, delim, lasts),
	register char *__restrict s _AND
	register const char *__restrict delim _AND
	char **__restrict lasts)
{
	return __strtok_r (s, delim, lasts, 1);
}
```

这个是newlib里面strtok_r函数的实现。
