Parameters
Processor number to interrupt (0-based).
Return Code
- NO_ERROR

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.
