linux get process name from pid within kernel

Question

hi i have used sys_getpid() from within kernel to get process id how can I find out process name from kernel struct? does it exist in kernel??

Answer 1

you can look at the special files in /proc//

For example, /proc//exe is a symlink pointing to the actual binary.

/proc//cmdline is a null-delimited list of the command line, so the first word is the process name.
