PARENT(3PVM) PVM Version 3.4 PARENT(3PVM)NAME
pvm_parent - Returns the tid of the process that spawned the calling process.
SYNOPSIS
C int tid = pvm_parent( void )
Fortran call pvmfparent( tid )
PARAMETERS
tid Integer returns the task identifier of the parent of the calling process. If the calling process was not created with pvm_spawn,
then tid = PvmNoParent.
DESCRIPTION
The routine pvm_parent returns the tid of the process that spawned the calling process. If the calling process was not created with
pvm_spawn, then tid is set to PvmNoParent.
EXAMPLES
C:
tid = pvm_parent();
Fortran:
CALL PVMFPARENT( TID )
ERRORS
This error condition can be returned by pvm_parent.
PvmNoParent
The calling process was not created with pvm_spawn.
PvmSysErr
Can't contact local pvmd.

SENDSIG(3PVM) PVM Version 3.4 SENDSIG(3PVM)NAME
pvm_sendsig - Sends a signal to another PVM process.
SYNOPSIS
C int info = pvm_sendsig( int tid, int signum )
Fortran call pvmfsendsig( tid, signum, info )
PARAMETERS
tid Integer task identifier of PVM process to receive the signal.
signum Integer signal number.
info Integer status code returned by the routine.
DESCRIPTION
The routine pvm_sendsig sends the signal number signum to the PVM process identified by tid. If pvm_sendsig is successful, info will be 0.
If some error occurs then info will be < 0.
pvm_sendsig should only be used by programmers with Unix signal handling experience. Many library functions (and in fact the PVM library
functions) cannot be called in a signal handler context because they do not mask signals or lock internal data structures.
Further caveat: the signal numbers passed between systems are not mapped - PVM assumes that signal 9 on one system is the same as on
another.
EXAMPLES
C:
tid = pvm_parent();
info = pvm_sendsig( tid, SIGKILL);
Fortran:
CALL PVMFBUFINFO( BUFID, BYTES, TYPE, TID, INFO );
CALL PVMFSENDSIG( TID, SIGNUM, INFO )
ERRORS
These error conditions can be returned by pvm_sendsig
PvmSysErr
pvmd not responding.
PvmBadParam
giving an invalid tid value.
