* [Mac]GetCurrentProcess()
*
* Discussion:
* Return the canonical process serial number to the caller.
*
* All applications ( things which can appear in the Dock or which
* are not documents and are launched by the Finder or Dock ) on Mac
* OS 10 have a unique process serial number. This number is
* created when the application launches, and remains until the
* application quits. Other system services, like AppleEvents, use
* the ProcessSerialNumber to specify an application.
*
* During launch, every application 'checks in' with the Process
* Manager. Before this checkin, the application can not receive
* events or draw to the screen. Prior to Mac OS 10.2, this 'check
* in' happened before the applications's main() function was
* entered. In Mac OS 10.2 and later, this 'check in' does not
* happen until the first time the application calls a Process
* Manager function, or until it enters CFRunLoopRun() for the main
* runloop. This allows tools and other executables which do not
* need to receive events to link against more of the higher level
* toolbox frameworks, but may cause a problem if the application
* expects to be able to retrieve events or use CoreGraphics
* services before this checkin has occurred.
*
* An application can force the connection to the Process Manager to
* be set up by calling any Process Manager routine, but the
* recommended way to do this is to call GetCurrentProcess() to ask
* for the current application's PSN. This will initialize the
* connection to the Process Manager if it has not already been set
* up and 'check in' the application with the system.
*
* This function is named MacGetCurrentProcess() on non Macintosh
* platforms and GetCurrentProcess on the Macintosh. However, even
* Macintosh code can use the MacGetCurrentProcess() name since
* there is a macro which maps back to GetCurrentProcess().
*
* Lastly, it is usually not necessary to call GetCurrentProcess()
* to get the 'current' process psn merely to pass it to another
* Process Manager routine. Instead, just construct a
* ProcessSerialNumber with 0 in highLongOfPSN and kCurrentProcess
* in lowLongOfPSN and pass that. For example, to make the current
* process the frontmost process, use ( C code follows )
*
* ProcessSerialNumber psn = { 0, kCurrentProcess };
*
* OSErr err = SetFrontProcess( & psn );
*
* If you need to pass a ProcessSerialNumber to another application
* or use it in an AppleEvent, you do need to get the canonical PSN
* with this routine.
*
* Parameters:
*
* PSN:
* Pass in where the current application process serial number
* should be returned.
*
* Result:
* An operating system status code.

* If the caller does not care about the process name or the process
