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

struct task_struct contains a member called comm, it contains executable name excluding path.

Get current macro from this file will get you the name of the program that launched the current process (as in insmod / modprobe).

Using above info you can use get the name info.
