Field descriptions

highLongOfPSN

The high-order long integer of the process serial number.

lowLongOfPSN

The low-order long integer of the process serial number.

The Process Manager uses process serial numbers to identify open processes. A process serial number is a 64-bit quantity whose structure is defined by the ProcessSerialNumber data type.

The meaning of the bits in a process serial number is internal to the Process Manager. You should not attempt to interpret the value of the process serial number. If you need to compare two process serial numbers, call the SameProcess function.
