The tsselect entry point provides the means for determining if specified events have occurred on the PCI MPQP device. This entry point is supported similar to the ddselect communications entry point.
The tsselect entry point functions with a 4-Port Multiprotocol Interface adapter that has been correctly configured for use on a qualified network. Consult adapter specifications for more information on configuring the adapter and network qualifications.

reventp | Returns events pointer. This parameter is passed by reference and is used by the tsselect entry point to indicate which of the selected events are true at the time of the call. |
