hello
I am reading the code of apache. Is there anybody who knows whether
ap_run_pre_connection() and ap_run_process_connection() are functions or
macro? and where is the definition for those two , as i can not find any
detailed code for them?
macros
The chase begins with http_connection.h:
/**
* This hook gives protocol modules an opportunity to set everything up
* before calling the protocol handler. All pre-connection hooks are
* run until one returns something other than ok or decline
* @param c The connection on which the request has been received.
* @param csd The mechanism on which this connection is to be read.
* Most times this will be a socket, but it is up to the module
* that accepts the request to determine the exact type.
* @return OK or DECLINED
*/
AP_DECLARE_HOOK(int,pre_connection,(conn_rec *c, void *csd))
/**
* This hook implements different protocols. After a connection has been
* established, the protocol module must read and serve the request. This
* function does that for each protocol module. The first protocol module
* to handle the request is the last module run.
* @param c The connection on which the request has been received.
* @return OK or DECLINED
*/
AP_DECLARE_HOOK(int,process_connection,(conn_rec *c))
What do you want to find out? The actual implementation isn't so
interesting. If you want to see how to implement your own connection
hook, see how the "process_connection" string is used in Apache in a
few macro invocations.
