SENDSIG

Section: PVM Version 3.4 (3PVM) Updated: 30 August, 1993 Local index Up

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.
