NAME

sys_tgkill - send signal to one specific thread

SYNOPSIS

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

ARGUMENTS

tgid

the thread group ID of the thread

pid

the PID of the thread

sig

signal to be sent

DESCRIPTION

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.
