FORTRAN synopsis

include 'mpif.h' or use mpi
MPI_ABORT(INTEGER COMM,INTEGER ERRORCODE,INTEGER IERROR)

Parameters

comm

is the communicator of the tasks to abort. (IN)

errorcode

is the error code returned to the invoking environment. (IN)

IERROR

is the FORTRAN return code. It is always the last argument.
