Functions
gchar *	url_escape (const gchar *url)
	Escape undesirable characters using xx, where xx is an hex code.

gchar *	url_escape_cntrl (gchar *url)
	Escape control characters using xx, where xx is an hex code.
gchar *	url_unescape (gchar *url, gboolean inplace)
	Unescape string, in-place if `inplace' is TRUE.

	Parse all the parameters in the URL query string.
const gchar *	url_params_get (url_params_t *up, const gchar *name)
	Get the value of a parameter, or NULL if the parameter is not present.
void	url_params_free (url_params_t *up)
	Dispose of the url_params_t structure.
gchar *	url_normalize (gchar *url, url_policy_t pol)
	Attention: NB: May modify ``url'' in all cased; pass a copy if necessary!

Function Documentation

gchar* url_escape (  const gchar *  url  )

Escape undesirable characters using xx, where xx is an hex code. Returns: argument if no escaping is necessary, or a new string otherwise.

gchar* url_escape_cntrl (  gchar *  url  )

Escape control characters using xx, where xx is an hex code. Returns: argument if no escaping is necessary, or a new string otherwise.

gint url_escape_into (  const gchar *  url, gchar *  target, gint  len )

Escape undesirable characters using xx, where xx is an hex code. This is done in the `target' buffer, whose size is `len'. Returns: amount of characters written into buffer (not counting trailing NUL), or -1 if the buffer was too small.

gchar* url_escape_query (  const gchar *  url  )

Same as url_escape(), but '+' are also escaped for the query string. Returns: argument if no escaping is necessary, or a new string otherwise.

gchar* url_normalize (  gchar *  url, url_policy_t  pol )

Attention: NB: May modify ``url'' in all cased; pass a copy if necessary! Returns: NULL if ``url'' isn't a valid resp. allowed URL. Otherwise, it returns either a pointer to the original URL or a g_malloc()ed modified copy which has to be g_free()ed. The URL is validated according to the specified policy. Unnecessary parts such as ":80" (for the port) and "/./" are removed: the hostname is forced to lowercase; a base URI "/" is appended if missing. This allows comparing different variants of the same URL to detect duplicates.

void url_params_free (  url_params_t *  up  )

Dispose of the url_params_t structure.

const gchar* url_params_get (  url_params_t *  up, const gchar *  name )

Get the value of a parameter, or NULL if the parameter is not present. The value returned has already been URL-unescaped.

url_params_t* url_params_parse (  gchar *  query  )

Parse all the parameters in the URL query string. All parameter values are stored in their URL-unescaped form, but parameter names are NOT un-escaped. Returns: an url_params_t object that can be queried for later... or NULL if the argument isn't valid encoded.

gchar* url_unescape (  gchar *  url, gboolean  inplace )

Unescape string, in-place if `inplace' is TRUE. Returns the argument if un-escaping is NOT necessary, a new string otherwise unless in-place decoding was requested. Returns: NULL if the argument isn't valid encoded.
