Break a string into substrings, or tokens, by inserting null characters in
place of specified delimiters.

char *strtok(char *s1, const char *s2);

Returns a pointer to the first character of a token (the first character in
s1 that does not appear in the set of characters of s2). If no token is
found, the null pointer is returned.
A sequence of calls to this function can be used to split up a string into
substrings (or tokens) by replacing specified characters with null char-
acters. The first time this function is invoked on a particular string, that
string should be passed in s1. After the first time, this function can con-
tinue parsing the string from the last delimiter by invoking it with a null
value passed in s1.
It skips all leading characters that appear in the string s2 (delimiters),
then skips all characters not appearing in s2 (this segment of charac-
ters is the token), and then overwrites the next character with a null
character, terminating the current token. The function strtok then
saves a pointer to the character that follows, from which the next
search will start. If strtok finds the end of the string before it finds a
delimiter, the current token extends to the end of the string pointed to
by s1. If this is the first call to strtok, it does not modify the string (no
null characters are written to s1). The set of characters that is passed
in s2 need not be the same for each call to strtok.
If strtok is called with a non-null parameter for s1 after the initial call,
the string becomes the new string to search. The old string previously
searched will be lost.
