RE: cancelling

[Bossom, John]

Check to see if the code base for pthread is wrapping
an exception handler around your thread mainline
(the original code had an internal routine called "threadStart"
which used Microsoft's Structured Exception Handling for catching all
exceptions raised in your thread.)
The cancel mechanism was implemented using this strategy.
Now, your thread is recognizing the cancel (the exception
hex value is human readable: BAD DEED) and should have
been caught by the threadStart wrapper, which would have
gracefully shut down your thread.

I am not familiar with the code base anymore so you will
have to ask others... ie Ross

Subject: cancelling


I'm trying to cancel a thread that is blocking
in pthread_cond_wait. When I do this, I get:
gdb: unknown target exception 0xebaddeed at 0x77e79b01

I'm using the precompiled snapshot 1999-11-02,
the rest of the program is compiled with the current
(as of two weeks ago) cygwin gcc (with -mno-cygwin).

What am I missing?

The thread I'm trying to cancel was created with pthread_create,
and internally the thread routine is started through
_pthread_threadStart, which should be fine.

The thread that tries to cancel is the initial thread, i.e.
the one that called _main.

I thought that the constant wasn't chosen arbitrarily :))

Announcing a commercial product based on pthread-win32

[Tristan Savatier]

PocketTV ( http://www.pockettv.com )

It is an MPEG Movie Player for Pocket PC devices (e.g.
iPaq, Cassiopeia, Jornada).

It is built on pthread-win32 (ported to Windows-CE).

Works flawlessly.

Thanks you all!
