pvm_sendsig - Sends a signal to another PVM process.
C int info = pvm_sendsig( int tid, int signum )
Fortran call pvmfsendsig( tid, signum, info )
- Integer task identifier of PVM process to receive the signal.
- Integer signal number.
- Integer status code returned by the routine.
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.
tid = pvm_parent();
info = pvm_sendsig( tid, SIGKILL);
CALL PVMFBUFINFO( BUFID, BYTES, TYPE, TID, INFO );
CALL PVMFSENDSIG( TID, SIGNUM, INFO )
These error conditions can be returned by pvm_sendsig
- pvmd not responding.
- giving an invalid tid value.
