Syntax

DioGetTriggerXEventSource (nMasterHandle, pnSource, pnStatus)

Parameters

Name	Type	Comments
nMasterHandle	SHORT	Master or File board handle.
pnSource	PSHORT	Values are: 0 The source is external event lines (default). 1 The source is the X register.
pnStatus	PSHORT	Returned status: 0 on success, negative number on failure.

Comments

The function is used to simulate external event lines. When nSource is 1, the X register value is used instead of external event lines on trigger, pause and conditional commands in the running vector. DioWriteXRegister can be used to set the value of the X register.

The following example returns the X register trigger source:

SHORT nStatus, nSource;

DioGetTriggerXEventSource (nMasterHandle, &nSource, &nStatus);
