pvm_getinst3

Usage

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.

Overview

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
