Hello, do not you know, can I rely on "constant" struct MHD_Connection *connection pointer passed to (*MHD_AccessHandlerCallback)? The constant is meant as not varying during a single connection. It is quite difficult to explain for me so let me outline the example :)
The problem: I need to access URI parameters in the response callback. The solution: The function (*MHD_AccessHandlerCallback) creates a response from callback by passing (*MHD_ContentReaderCallback) to the function MHD_create_response_from_callback. The pointer to struct MHD_Connection * is stored in the crc_cls (extra argument to crc). In the (*MHD_ContentReaderCallback) callback, the void *cls is casted to struct MHD_Connection * and call MHD_get_connection_values to get values. The problem appears when the libmicrohttpd somehow reallocates the connection pointer internally during the next call of (*MHD_AccessHandlerCallback) or (*MHD_ContentReaderCallback). I remind, I think only one connection => *con_cls != NULL previusly set to something different from NULL. The story above can be also summarized to this question: How can I access the connection information from the response callback? Best Martin
