I am having huge troubles with SunOS's LWP library (using SunOS 4.0.3 on a SS-1) and I would urgently like to hear anybody's experiences with using this library. In particular, I'm curious to find out whether anyone has experienced the library failing to resume (using lwp_resume()) threads which have been suspended (using lwp_suspend()). I'm sure that the threads are being suspended properly and that the call to lwp_resume() is ok (i.e. it is called with a valid thread id) but sometimes the threads just don't resume. In a last ditch effort to fix my problem I tried to get the thread to be suspended to wait on a message (using msg_recv()) and then have the other thread restart it by sending it a message. This worked a little better, but the threads still frequently fail to rendezvous and the program grinds to a halt. I've had little success in finding out anyone's experiences with this library. Is this because no-one uses it? Is it broken? If so, are there any other libraries which provide similar functions with the added novelty of actually working? james jamesp@bison.cs.uwa.oz.au
