SameProcess

SameProcess
Header:	Processes.h		Carbon status:	Supported

Determines whether two process serial numbers specify the same process.

OSErr SameProcess (
    const ProcessSerialNumber *PSN1, 
    const ProcessSerialNumber *PSN2, 
    Boolean *result
);

PSN1: A process serial number.
PSN2: A process serial number.
result: On return, a pointer to a Boolean value which is TRUE if the process serial numbers passed in PSN1 and PSN2 refer to the same process; otherwise FALSE.

function result: A result code.

DISCUSSION

Do not attempt to compare two process serial numbers by any means other than the SameProcess function, because the interpretation of the bits in a process serial number is internal to the Process Manager.

The values of PSN1 and PSN2 must be valid process serial numbers returned from LaunchApplication, GetNextProcess, GetFrontProcess, GetCurrentProcess, or a high-level event. You can also use the constant kCurrentProcess to refer to the current process.
