[dtrace-discuss] how to use Dtrace to find out "write" blocks.
we use /dev/poll to poll message from network. but write() to /dev/poll and ioctl() /dev/poll will block each other when monitor message. how can we use dtrace to find this in our program. attachment is an program having two threads, one is listening for new connection and write to /dev/poll and another is using ioctl() to monitor new messages. they are already blocked each other, but i want to know how to use dtrace to found this. thanks. -- This message posted from opensolaris.org -------------- next part -------------- A non-text attachment was scrubbed...
