MPI_Request_get_status function

Nondestructive test for the completion of a request.

Syntax

int MPIAPI MPI_Request_get_status(
        MPI_Request request,
  _Out_ int         *flag,
  _Out_ MPI_Status  *status
);

Parameters

  • request
    Communication request.

  • flag [out]
    True if operation has completed.

  • status [out]
    Status object, or MPI_STATUS_IGNORE.

Return value

Returns MPI_SUCCESS on success. Otherwise, the return value is an error code.

In Fortran, the return value is stored in the IERROR parameter.

    MPI_REQUEST_GET_STATUS( REQUEST, FLAG, STATUS, IERROR)
        INTEGER REQUEST, STATUS(MPI_STATUS_SIZE), IERROR

Remarks

Unlike MPI_Test, MPI_Request_get_status does not deallocate or deactivate the request. A call to one of the test/wait routines or MPI_Request_free should be made to release the request object.
