AcxCircuitStopIoWithTag macro (acxcircuit.h)

  • Article

The AcxCircuitStopIoWithTag function is used to signal to the operating system to temporarily stop circuit I/O. This allows the driver a short period of time to run time sensitive tasks, and then resume IO after the execution of time sensitive code is complete.

Syntax

void AcxCircuitStopIoWithTag(
   Circuit,
   Flags,
   Tag
);

Parameters

Circuit

An existing ACXCIRCUIT circuit object. (For more information about ACX objects, see Summary of ACX Objects.

Flags

Stop IO flags defined by the ACX_STOP_IO_FLAGS enumeration.

Currently no flags are defined, set this to AcxStopIoNoFlags.

Tag

An optional ObjectTag that is a driver-defined value that the framework stores as an identification tag for the ACX driver. Specify the pointer of the object taking the reference.

Return value

None
