_VCOMM_SetCommEventMask
include vcomm.inc
VxDCall _VCOMM_SetCommEventMask, <hPort, dwMask, <OFFSET32 dwEvents>>
or eax, eax
jz error_handler
Sets the event mask and the location of the event variable.
- Returns TRUE if successful, FALSE otherwise. For extended error information, use _VCOMM_GetLastError.
- hPort
- Handle of a communications resource.
- dwMask
- The event mask for the communications resource. For a list of events, see CommNotifyProc.
- dwEvents
- Address of the event variable. Because the port driver updates the event variable at interrupt time, it must be in locked memory. If this parameter is NULL, the location of the event variable is not changed.
