[Mingw-users] Strange Behaviour of open()

[Kiran B. <kir...@wi...>]

I wrote a simple device drover using mingw.
I then loaded the driver successfully.
The driver has DBG statement in both disptachCreate and dispatchClose
function.

I wrote an application (using Mingw) that does just opens and closes the
device using CreateFile and CloseHandle.
On execution, the DBG window shows=20
"Create Called"
"Close Called"

Now if I write an application (using Mingw) using open() and close()
calls, and execute it, I see

"Create Called"
"Close Called"

Printed six times !!!

Can some throw light on this strange behaviour?

Thanx
 Kiran
