Error 183 is ERROR_ALREADY_EXISTS.  The description text is misleading.  In
the case of named Kernel objects (mutexes, semaphores, mailslots, etc.),
ERROR_ALREADY_EXISTS is not an actual error.  It simply means that the named
object already exists in memory, and the function creating the object will
return a handle to the existing object rather than creating a new object
instance.

When you get 183, did CreateMailSlot() return INVALID_HANDLE_VALUE, or did
it actually return something else?  Most likely, it is returning an actual
valid handle.

Not true.

The length of the name is not limited.

It has nothing to do with the compiler.  You are calling a Win32 API
function.  It doesn't matter which programming language is calling the
function because they all call it the same way.
