SameProcess

SameProcess Compare two process serial numbers

OSErr SameProcess(PSN1,PSN2, result);

ProcessSerialNumber *PSN1 ; pointer to first process serial number

ProcessSerialNumber *PSN 2 ; pointer to second process serial number

Boolean *result ; TRUE=same process

returns Error Code; 0=no error

You use SameProcess to compare two process serial numbers and to

determine whether they refer to the same process.

PSN1 is a pointer to a valid process serial number returned from

GetCurrentProcess , or a high level event. You can also use the

constant kCurrentProcess to return to the current process.

PSN2 is a valid process serial number returned from

GetCurrentProcess , or a high level event. You can also use the

constant kCurrentProcess to return to the current process.

result is a pointer to a Boolean value. If the process serial numbers

specified in the PSN1 and PSN2 parameters refer to the same

process, the SameProcess function returns TRUE in the result

parameter; otherwise, it returns FALSE in the result parameter.

Returns: an operating system Error Code.

noErr (0) No error

paramErr (-50) Process serial number is invalid

Notes: When you compare two process serial numbers, use the SameProcess

function rather than any other means, because the interpretation of the bits

in a process serial number is internal to the Process Manager.
