Hello,
While trying to use the option MHD_OPTION_URI_LOG_CALLBACK to get the
full url from the client, the documentation says:
"the return value will be passed as (*con_cls) in calls to the
MHD_AccessHandlerCallback when this request is processed later;
returning a value of NULL has no special significance (however, note
that if you return non-NULL, you can no longer rely on the first call to
the access handler having NULL == *con_cls on entry;)"
The need is to store the full url called by the client in a char * variable.
In my program, I detect the first iteration of MHD_AccessHandlerCallback
by testing if con_cls is NULL:
https://github.com/babelouest/ulfius/blob/master/src/ulfius.c#L111
Is there another way for MHD_AccessHandlerCallback to detect it's in the
first iteration, so I can properly use con_cls and the option
MHD_OPTION_URI_LOG_CALLBACK ?
/Nicolas
