Here is the call graph for this function:

Here is the caller graph for this function:

InitHTTPServer()

bool InitHTTPServer

(

)

Initialize HTTP server.

Call this before RegisterHTTPHandler or EventBase().

Here is the caller graph for this function:

InterruptHTTPServer()

void InterruptHTTPServer

(

)

Interrupt HTTP server threads.

Here is the caller graph for this function:

RegisterHTTPHandler()

void RegisterHTTPHandler	(	const std::string &	prefix,
		bool	exactMatch,
		const HTTPRequestHandler &	handler )

Register handler for prefix.

If multiple handlers match a prefix, the first-registered one will be invoked.

Here is the call graph for this function:

Here is the caller graph for this function:

StartHTTPServer()

void StartHTTPServer

(

)

Start HTTP server.

This is separate from InitHTTPServer to give users race-condition-free time to register their handlers between InitHTTPServer and StartHTTPServer.

Here is the caller graph for this function:

StopHTTPServer()

void StopHTTPServer

(

)

Stop HTTP server.
