Re: async_private + ReadFile() etc. immediate completion

[Mike McCormack]

Hi Martin,

I haven't tried the patch yet, but from Lawson's trace it looks like
the completion routine for ReadFileEx is not being called.

Some notes:
* the 16bit Comm code expects ReadFileEx to be unconditionally
overlapped, and always call the completion function when the operation
completes.

* the completion function starts another ReadFileEx, and sends a
WM_COMMNOTIFY message to the 16bit app.

i had a look at you patch, but i haven't applied it yet, so it's
difficult for me to see any problems... i'll have a go later today.

Mike

async_private + ReadFile() etc. immediate completion

[Martin Wilck]

Here are 2 small patches.
Both apply on top of the patch I sent yesterday  which started this
thread.

1) fixes a bug that I discovered myself,
2) Adds TRACES to several functions to simplify debugging.

2) Is not meant for applying to CVS!!!

However, Lawson it would be nice if you produce a new trace with these two
patches applied.

start your app with --debugmsg trace+file,trace+thread,trace+comm.

Regards,
Martin
