Hello, The tick in Linux is 10ms. In my userspace program can I have a timeout value less than this granularity. Example a timeout value of 4 milliseconds. If this is possible, how is this taken care by the kernel ? thanks, daniel. -- Get your free email from www.linuxmail.org Powered by Outblaze -- Kernelnewbies: Help each other learn about the Linux kernel.
