// Defines strtok(), which tokenizes a string via repeated calls.
//
// strtok() considers the string to consist of a sequence of zero or more text
// tokens separated by spans of one or more control characters.  The first call,
// with a string specified, returns a pointer to the first character of the
// first token, and will write a null character into the string immediately
// following the returned token.  Subsequent calls with a null string argument
// will work through the string until no tokens remain.  The control string
// may be different from call to call.  When no tokens remain in the string, a
// null pointer is returned.
