* @url_string: The string containing the URL to scan
|
|
*
|
|
* This routine takes a gchar and parses it as a
|
|
* URL of the form:
|
|
* protocol://user;AUTH=mech:password@host:port/path
|
|
* There is no test on the values. For example,

* "port" can be a string, not only a number!
|
|
* The Gurl structure fields are filled with
|
|
* the scan results. When a member of the
|
|
* general URL can not be found, the corresponding
|
|
* Gurl member is NULL.
|
|
* Fields filled in the Gurl structure are allocated
|
|
* and url_string is not modified.
|
|
*
|
|
* Return value: a Gurl structure containing the URL items.
