- A string representation of the signal
- Name of the probe point
- A task handle to the signal recipient
- The thread group ID of the thread receiving the kill signal
- The specific kill signal sent to the process
- The name of the signal recipient
- The PID of the thread receiving the kill signal
The tgkill call is similar to tkill, except that it also allows the caller to specify the thread group ID of the thread to be signalled. This protects against TID reuse.
