GETINST

NAME

pvm_getinst - Returns the instance number in a group of a PVM process.

SYNOPSIS

C       int inum = pvm_getinst( char *group, int tid )



Fortran call pvmfgetinst( group, tid, inum )

PARAMETERS

group: Character string group name of an existing group.
tid: Integer task identifier of a PVM process.
inum: Integer instance number returned by the routine. Instance numbers start at 0 and count up. Values less than zero indicate an error.

DESCRIPTION

The routine pvm_getinst takes a group name group and a PVM task identifier tid and returns the unique instance number that corresponds to the input. It can be called by any task whether in the group or not. If pvm_getinst is successful, inum will be >= 0. If some error occurs then inum will be < 0.

EXAMPLES

C:
        inum = pvm_getinst( "worker", pvm_mytid() );
        --------
        inum = pvm_getinst( "worker", tid[i] );

Fortran:
        CALL PVMFGETINST( 'GROUP3', TID, INUM )

ERRORS

These error conditions can be returned by pvm_getinst

PvmSysErr: pvmd was not started or has crashed.
PvmBadParam: giving an invalid tid value.
PvmNoGroup: giving a non-existent group name.
PvmNotInGroup: specifying a group in which the tid is not a member.
