Function Documentation

int main (  void   )

Main entry of our application. Nut/OS automatically calls this entry after initialization. This routine will do all required initialization, start some background threads and then process incoming HTTP requests together with the concurrently running background threads.

void Service (  void   )

Process a single HTTP request. This routine performs the whole cycle of a HTTP request. Creating a socket. Listening on the defined port. Processing the request. Closing the socket. Definition at line 100 of file webport.c. References HTTP_PORT, and LOW_MEM_MARK. Referenced by main(), and ServiceThread().

ServiceThread (  void *  arg  )

Background thread to process HTTP requests. This thread calls Service() in an endless loop. Definition at line 152 of file webport.c. References Service(). Referenced by main().
