bool mt_send_handle::forceSend ( NodeId nodeId )

virtual

This is used in case send buffer gets full, to force an emergency send, hopefully freeing up some buffer space for the next signal.

Implements TransporterSendBufferHandle.

Here is the call graph for this function:

Uint32 * mt_send_handle::getWritePtr	(	NodeId	node,
		Uint32	lenBytes,
		Uint32	prio,
		Uint32	max_use
	)

virtual

Get space for packing a signal into, allocate more buffer as needed.

The max_use parameter is a limit on the amount of unsent data (whether delivered through get_bytes_to_send_iovec() or not) for one node; the method must return NULL rather than allow to exceed this amount.

Implements TransporterSendBufferHandle.

Definition at line 2210 of file mt.cpp.

Uint32 mt_send_handle::updateWritePtr	(	NodeId	node,
		Uint32	lenBytes,
		Uint32	prio
	)

virtual

Called when new signal is packed.

Returns number of bytes in buffer not yet sent (this includes data that was made available to send with get_bytes_to_send_iovec(), but has not yet been marked as really sent from bytes_sent()).

Implements TransporterSendBufferHandle.
