Hello everyone. I'm currently working on a java project involving native code. The problem I have is the following. I want to do reads in the native code, and this read is intercepted by libjava.so. This is fine and usually works as expected with green threads. However, in our code we have set the file descriptor to be non-blocking with ioctl(... FIONBIO ...). However java doesn't realize that the file descriptor is nonblocking, and so doesn't return control flow to the native code until something has been read (essentially implementing a blocking call to read with nonblocking read in order to allow other threads to run. I tried using fcntl (fd, F_SETFL, fcntl (fd, F_GETFL) | O_NONBLOCK) too, because libjava.so does replace the fcntl (whereas it does not replace ioctl) , but this didn't seem to work either. Anyone have any ideas on this? I've tried using the native threads implementation, but had problems with it. Thanks in advance, Peter Godman
