Q.  How do I use strtok_r() ?

A.  Here's an example.  This function uses strtok_r() to break up a string
they is delimited by semi-colons and commas.

void BreakOnPunct(char *s)
{
	const char *	delim = ";,";
	char *		save;
	char *		p;

	for (p = strtok_r(s, delim, &save); p; p = strtok_r(NULL, delim, &save))
	{
		printf("chunk=%s\n", p);
	}
}
