char* soup_form_encode_hash ( GHashTable* form_data_set )
form_data_set into a value of type “application/x-www-form-urlencoded”.
Encodes as defined in the HTML 4.01 spec.
Note that the HTML spec states that “The control names/values are
listed in the order they appear in the document.” Since this method
takes a hash table, it cannot enforce that; if you care about the
ordering of the form fields, use
A hash table containing name/value pairs (as strings)
|The data is owned by the caller of the function.|
