gc_GetMetaEvent( ) — retrieve event information for the current SRL event Cautions Errors The gc_GetMetaEvent( ) function must be the first function called before processing any Global Call event. For Windows ® applications, when using the extended asynchronous model, the gc_GetMetaEventEx( ) function must be the first function called before processing any Global Call event. For all other Windows ® models, use the gc_GetMetaEvent( ) function. An application should call the gc_GetMetaEvent( ) function only once for a given event. Calling the function more than once will result in data corruption or an access violation. The event must be processed entirely in the same thread or all information about the event must be retrieved before processing the event in another thread. The gc_GetMetaEvent( ) and gc_GetMetaEventEx( ) functions should not be used in the same application. If this function returns
etrieve event information for the current SRL event — gc_GetMetaEvent( ) To retrieve and process information associated with an event, the following example code can be used. This code returns the event type, event data pointer, event length and event device associated with the event from either the handler or after a sr_waitevt( ) function call. retcode = gc_GetMetaEvent(&metaevent); if (retcode
