Curious about the -9
I was talking to a coworker and we got into a discussion about the -9. No one knew where the -9 came from and it's not in the man. I suggested that it was like counting to 10 (0-9) and you finally get to the point that that's it, the durned thing is going to die. So how did the -9 come to mean "NOW!" without reservation? It looks like it has the same impact as -KILL or -s KILL. But how did the -9 become that?

pvm_kill
KILL(3PVM) PVM Version 3.4 KILL(3PVM)
NAME
pvm_kill - Terminates a specified PVM process.
SYNOPSIS
C int info = pvm_kill( int tid )
Fortran call pvmfkill( tid, info )
PARAMETERS
tid Integer task identifier of the PVM process to be killed (not yourself).
info Integer status code returned by the routine. Values less than zero indicate an error.
DESCRIPTION
The routine pvm_kill sends a terminate (SIGTERM) signal to the PVM process identified by tid. In the case of multiprocessors the terminate
signal is replaced with a host dependent method for killing a process. If pvm_kill is successful, info will be 0. If some error occurs
then info will be < 0.
pvm_kill is not designed to kill the calling process. To kill yourself in C call pvm_exit() followed by exit(). To kill yourself in For-
tran call pvmfexit followed by stop.
EXAMPLES
C:
info = pvm_kill( tid );
Fortran:
CALL PVMFKILL( TID, INFO )
ERRORS
These error conditions can be returned by pvm_kill
PvmBadParam
giving an invalid tid value.
PvmSysErr
pvmd not responding.
