handle

Question

hello,

I'm trying to use the naughter class to use the serial communication. I have a bug in my application.

I created the serial communication object and opened the communication in one thread, and I'm trying to access it from another thread.
I sent to this other thread the handle of the communication. I double checked, it's the same handle.
But the next read I try to use from that second thread returns a getLastError = 6, which apparently is because the handle is incorrect.
But it's the handle that was retrieved using HANDLE() so I don't understand what's wrong.

Please help me.

Thanks

Answer 1

Does your "next read" comment mean you are trying to read from more than one thread?  Do you have two serial objects, one for reading and one for writing?

Answer 2

try to use DuplicateHandle Function. If you have source code, please post the code.

I fixed this HANDLE(m_port) error using detach (which also returns the handle) followed by attach again. It just happens that HANDLE() and detach don't return the same value. I don't really care why though, because it works now. I'll just refrain myself from using HANDLE().
