sys_tgkill(9)

NAME

sys_tgkill - send signal to one specific thread

SYNOPSIS

long sys_tgkill(int tgid, int pid, int sig);

ARGUMENTS

tgid

the thread group ID of the thread

pid

the PID of the thread

This syscall also checks the tgid and returns -ESRCH even

if the PID exists but it's not belonging to the target process

anymore. This method solves the problem of threads exiting and

PIDs getting reused.
