Signals. The common communication channel between user space program and kernel is given by the system calls. But there is a different channel, that of the signals, used both between user processes and from kernel to user process. 5.1 Sending signals A program can signal a different program using the kill() system call with prototype

May 01, 2000 · The data structures in the kernel to support signals in Linux are to be found in the task structure. Here are the most common elements of said structure pertaining to signals: current-->sig are the signal handlers. sigmask_lock is a per-thread spinlock which protects the signal queue and atomicity of other signal operations.
