Please reply to the whole list in future; that way someone else who might know the answers to your question can respond. > ' Is there any way in kernel space to wait for any file/socket descriptor to > change instead of blocking continuously ??? ' Tell us what exactly you are trying to do; why use a socket, why not something like shared memory to communicate between modules? Or kernel notifiers (IIRC: linux/notifier.h). Also, using fd's in kernel is not recommended. Use file structures. You could create a user-land app that ioctl()'s into module_1; module_1 requests user_app to access module_2 and it does so through another ioctl(). ./h -- Operating Systems and Computer Architecture Research - University of Cincinnati http://www.ececs.uc.edu/~mohapth -- Kernelnewbies: Help each other learn about the Linux kernel.
