strsep - extract token from string
char *strsep(char **stringp, const char *delim);
If *stringp is NULL, the strsep() function returns NULL and does noth-
ing 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 overwriting 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 cannot handle empty fields. However, strtok() con-
forms to ANSI-C and hence is more portable.
This function suffers from the same problems as strtok(). In particu-
lar, it modifies the original string. Avoid it.
