ierror
: Fortran only: Error status (integer).
This function invokes the error handler assigned to the communicator comm with the supplied error code errorcode. If the error handler was successfully called, the process is not aborted, and the error handler returns, this function returns MPI_SUCCESS.
Users should note that the default error handler is MPI_ERRORS_ARE_FATAL. Thus, calling this function will abort the processes in comm if the default error handler has not been changed.
