7

SYNOPSIS

9       long sys_tgkill(pid_t tgid, pid_t pid, int sig);
10

ARGUMENTS

12       tgid
13           the thread group ID of the thread
14
15       pid
16           the PID of the thread
17
18       sig
19           signal to be sent
20

DESCRIPTION

22       This syscall also checks the tgid and returns -ESRCH even if the PID
23       exists but it's not belonging to the target process anymore. This
24       method solves the problem of threads exiting and PIDs getting reused.
