win32.base.messages.BeginUpdateSession

BeginUpdateSession is available since version 1.0.

Prototype:

null-returned BeginUpdateSession()

Description:

Caches blocks of messages; instead of sending multiple blocks containing messages, the messages are grouped. When calling wait_message_ID alias WaitMessage or getting a property, the buffer will be flushed. The number of calls to BeginUpdateSession must match the number of calls of EndUpdateSession; when this happens, the data will be flushed over the network, and all the messages will be send in one virtual packet (conserving both speed, and bandwidth).

Return value:

Returns null.
