How can i know it this running process handle value?

Also, dedndave, your "optimized" version incurs two stack pointer arithmetic operations and two memory bus access (i.e. potential cache misses), not to mention lengthy dependencies.  The OR way is one single ALU uop, which can execute in half a clock cycle (or a third of one, on Core 2).  Like my girlfriend says, size isn't everything (though she's probably just being nice  :'( )

After all that cruel Microsoft-bashing, finally some positive remarks: short and crispy, and fast, too! This is probably the best API call in Windows history, I think we should make it obligatory for every decent assembler proggie.
