Function Documentation

void MHD_connection_close ( struct MHD_Connection connection,
enum MHD_RequestTerminationCode  termination_code 
)
int MHD_connection_handle_idle ( struct MHD_Connection connection  ) 

This function was created to handle per-connection processing that has to happen even if the socket cannot be read or written to. All implementations (multithreaded, external select, internal select) call this function.

Parameters:
connection connection to handle
Returns:
MHD_YES if we should continue to process the connection (not dead yet), MHD_NO if it died

int MHD_connection_handle_read ( struct MHD_Connection connection  ) 

This function handles a particular connection when it has been determined that there is data to be read off a socket. All implementations (multithreaded, external select, internal select) call this function to handle reads.

Parameters:
connection connection to handle
Returns:
always MHD_YES (we should continue to process the connection)

This function handles a particular connection when it has been determined that there is data to be read off a socket.

Parameters:
connection connection to handle
