so I am thinking this becomes a little bit too complicated and we are
overloading this. Here is my idea on how to make this simpler.
struct _GWebResult;
typedef struct _GWebResult GWebResult;
typedef gboolean (*GWebResultFunc) (guint16 status, GWebResult *result,
gpointer user_data);
guint g_web_request(GWeb, GWebMethod method, const char *url,
GWebResultFunc, gpointer user_data);
So essentially we are creating a new GWebResult object that represents
our transaction/request.
Then we can have these functions to be used inside the result callback.
gboolean g_web_result_get_header(GWebResult *result,
const char *header, const char **value);
gboolean g_web_result_get_fragment(GWebResult *result,
const guint8 **fragment, gsize *length);
The get_header function will be always valid since we keep all headers
in the GWebResult object for the time of the transaction. And the
get_fragment returns the current buffer value.
And of course the result function has a return value. If returning FALSE
then we just stop the transaction right away. So after we received the
headers we can call this once with empty fragment buffer and when we
have all details we just stop it. If we return TRUE then the transaction
continues until we have received the full body.
Also the status will indicate if we are done or not. A status of 100
indicates that there is more to come. And every other status is either
200 for success or an error code. Of course the return value only
matters if the status is 100 since otherwise the transaction is over
anyway.
What do you think?
Regards
Marcel
