strsep - extract token from string
char *strsep(char **stringp, const char *delim);
If *stringp is NULL, the strsep() function returns NULL and does nothing else. Otherwise,
this function finds the first token in the string *stringp, where tokens are delimited by
symbols in the string delim. This token is terminated with a `\0' character (by overwrit-
ing the delimiter) 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.
The strsep() function was introduced as a replacement for strtok(), since the latter can-
not handle empty fields. However, strtok() conforms to ANSI-C and hence is more portable.
This function suffers from the same problems as strtok(). In particular, it modifies the
original string. Avoid it.
