static int internal_add_connection ( struct MHD_Daemon daemon,
int  client_socket,
const struct sockaddr *  addr,
socklen_t  addrlen,
int  external_add 
)
static

Add another client connection to the set of connections managed by MHD. This API is usually not needed (since MHD will accept inbound connections on the server socket). Use this API in special cases, for example if your HTTP server is behind NAT and needs to connect out to the HTTP client.

The given client socket will be managed (and closed!) by MHD after this call and must no longer be used directly by the application afterwards.

Per-IP connection limits are ignored when using this API.

Parameters
daemondaemon that manages the connection
client_socketsocket to manage (MHD will expect to receive an HTTP request from this socket next).
addrIP address of the client
addrlennumber of bytes in addr
external_addperform additional operations needed due to the application calling us directly
Returns
MHD_YES on success, MHD_NO if this daemon could not handle the connection (i.e. malloc failed, etc). The socket will be closed in any case; 'errno' is set to indicate further details about the error.

Here is the caller graph for this function:

void MHD_suspend_connection ( struct MHD_Connection connection)

Suspend handling of network data for a given connection. This can be used to dequeue a connection from MHD's event loop (external select, internal select or thread pool; not applicable to thread-per-connection!) for a while.

If you use this API in conjunction with a internal select or a thread pool, you must set the option MHD_USE_PIPE_FOR_SHUTDOWN to ensure that a resumed connection is immediately processed by MHD.

Suspended connections continue to count against the total number of connections allowed (per daemon, as well as per IP, if such limits are set). Suspended connections will NOT time out; timeouts will restart when the connection handling is resumed. While a connection is suspended, MHD will not detect disconnects by the client.

The only safe time to suspend a connection is from the MHD_AccessHandlerCallback.

Finally, it is an API violation to call MHD_stop_daemon while having suspended connections (this will at least create memory and socket leaks or lead to undefined behavior). You must explicitly resume all connections before stopping the daemon.

Parameters
connectionthe connection to suspend
