Generate an inter-processor interrupt.
This function is used to generate an inter-processor interrupt. All inter-processor hardware dependencies should be fully initialized before the first GenIPI is called.
- Mode
- Called in Kernel, and Interrupt Mode.
Syntax
PSD_GEN_IPI <keywords>
Parameters
Processor number to interrupt (0-based).
Return Code
- NO_ERROR
- if the IPI was generated.
- -1
- if the IPI was not generated.
Remarks
OS/2 guarantees that the GenIPI function will not be called to interrupt a processor that has not finished processing any previous IPIs.
- This function is not required for OS/2 to execute with one processor, but it is required for OS/2 to use multiple processors.
- This function can not call a PSD help that may block.
