I am working on a Linux embedded project at the moment with one simple small requirement : when a certain event occurs within a kernel driver, I need to locate a listening user-space process and signal it somehow.
(1) How can I locate the PID of the specific process I want to handle this ? Can I query for the PID by name ?
(2) Once I have the PID, is it simply a matter of using sys_signal() to send the signal to the process ?
Thanks in advance for any help possible.
