View source for PSD GEN IPI

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.
