NKSendInterProcessorInterrupt (Compact 2013)

3/28/2014

This function sends a platform-specific interprocessor interrupt (IPI) to the specified processor.

Syntax

void
    NKSendInterProcessorInterrupt
    (
            DWORD dwType,
            DWORD dwTarget,
            DWORD dwCommand,
            DWORD dwData
    );

Parameters

• dwType
  Type of IPI to be sent. The following table shows possible values.

  Value	Description
  IPI_TYPE_ALL_BUT_SELF	The IPI is to be sent to all other processors.
  IPI_TYPE_ALL_INCLUDE_SELF	The IPI is to be sent to all processors.
  IPI_TYPE_SPECIFIC_CPU	The IPI is to be sent to the specified processor.

• dwTarget
  Specifies the hardware ID of the processor to which the IPI is to be sent. This parameter is used only if dwType is set to IPI_TYPE_SPECIFIC_CPU. Otherwise, it is ignored.

• dwCommand
  Platform-specific IPI command to be sent. This value must be equal to or greater than OEM_FIRST_IPI_COMMAND. This value is passed to the platform-specific IPI handler (the pfnIpiHandler variable of OEMGlobal) for the specified processor.

• dwData
  OEM-defined 32-bit value to be passed to the IPI handler for the specified processor.

Return Value

None.

Remarks

The dwCommand and dwData parameters are passed to the IPI handler running on the specified processor.
