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 )
