I want to send a message to a thread to close and am attempting to use the CBL_THREAD_IDDATA_ALLOC and CBL_THREAD_IDDATA_GET routines. I am am getting an exception error when calling CBL_THREAD_IDDATA_GET after creating the and the intellisense is saying there is no routine with this signature. I was going by the example from the documentation. I then created a new project using the example exactly as written and I get the same error. Is there a bug in this approach?

    This is the same bug that Robert pointed out on your previous post.

    It has to do with the usage thread-pointer not being mapped correctly to a .NET IntPtr data type which is required under the covers.

    If you change the call so that it uses an IntPtr it should work OK.

            01 sub-handle       usage thread-pointer.

            01  IntPtr type System.IntPtr.

                  set IntPtr to sub-handle as type System.IntPtr

                  call 'CBL_THREAD_IDDATA_GET' using sub-iddata-ptr

                                    by value IntPtr

                 ...

    Thanks Chris

    I thought i had tried that in my program, but I guess I didn't. Thanks again fro your help. If you know of an easier way for two threads to communicate please let me know.
