strsep - extract token from string
char *strsep(char **stringp, const char *delim);
Since glibc 2.19:
Glibc 2.19 and earlier:
If *stringp is NULL, the strsep() function returns NULL and does nothing else. Otherwise, this function finds the first token in the string *stringp, that is delimited by one of the bytes in the string delim. This token is terminated by overwriting the delimiter with a null byte ('\0'), and *stringp is updated to point past the token. In case no delimiter was found, the token is taken to be the entire string *stringp, and *stringp is made NULL.
The strsep() function returns a pointer to the token, that is, it returns the original value of *stringp.
For an explanation of the terms used in this section, see attributes(7).

Be cautious when using this function. If you do use it, note that:
- This function modifies its first argument.
- This function cannot be used on constant strings.
- The identity of the delimiting character is lost.
