30 * Here we deal with URLs following the general scheme:
31 * protocol://user;AUTH=mech:password@host:port/name
32 * where name is a path-like string (ie dir1/dir2/....) See RFC 1738
33 * for the complete description of Uniform Resource Locators. The
34 * ";AUTH=mech" addition comes from RFC 2384, "POP URL Scheme".
38 * recover the words between #'s or ?'s after the path

66 * soup_uri_new: create a SoupUri object from a string
68 * @uri_string: The string containing the URL to scan
70 * This routine takes a gchar and parses it as a
72 * protocol://user;AUTH=mech:password@host:port/path?querystring
73 * There is no test on the values. For example,
74 * "port" can be a string, not only a number!
75 * The SoupUri structure fields are filled with
76 * the scan results. When a member of the
77 * general URL can not be found, the corresponding
78 * SoupUri member is NULL.
79 * Fields filled in the SoupUri structure are allocated
80 * and url_string is not modified.
82 * Return value: a SoupUri structure containing the URL items.
