SENDSIG (3)
Sends a signal to another PVM process.
SYNOPSIS
B
C int info = pvm_sendsig( int tid, int signum )
Fortran call pvmfsendsig( tid, signum, info )
PARAMETERS
Integer task identifier of PVM process to receive the signal.
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
giving an invalid tid value.
