MPI_Request_get_status(3)						MPI						 MPI_Request_get_status(3)

NAME

       MPI_Request_get_status -  Nondestructive test for the completion of a Request

SYNOPSIS

       int MPI_Request_get_status(MPI_Request request, int *flag, MPI_Status *status)

INPUT PARAMETER

       request
	      - request (handle).  May be MPI_REQUEST_NULL .

OUTPUT PARAMETERS

       flag   - true if operation has completed (logical)
       status - status object (Status).  May be MPI_STATUS_IGNORE .

NOTES

       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.

THREAD AND INTERRUPT SAFETY

       This routine is thread-safe.  This means that this routine may be safely used by multiple threads without the need  for	any  user-provided
       thread  locks.  However, the routine is not interrupt safe.  Typically, this is due to the use of memory allocation routines such as malloc
       or other non-MPICH runtime routines that are themselves not interrupt-safe.

NOTES FOR FORTRAN

       All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an additional argument ierr at the end of the argument  list.   ierr
       is  an integer and has the same meaning as the return value of the routine in C.  In Fortran, MPI routines are subroutines, and are invoked
       with the call statement.

       All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran.

ERRORS

       All MPI routines (except MPI_Wtime and MPI_Wtick ) return an error value; C routines as the value of the function and Fortran  routines	in
       the  last  argument.  Before the value is returned, the current MPI error handler is called.  By default, this error handler aborts the MPI
       job.  The error handler may  be	changed  with  MPI_Comm_set_errhandler	(for  communicators),  MPI_File_set_errhandler	(for  files),  and
       MPI_Win_set_errhandler  (for  RMA  windows).   The  MPI-1 routine MPI_Errhandler_set may be used but its use is deprecated.  The predefined
       error handler MPI_ERRORS_RETURN may be used to cause error values to be returned.  Note that MPI does not guarentee that an MPI program can
       continue past an error; however, MPI implementations will attempt to continue whenever possible.

       MPI_SUCCESS
	      - No error; MPI routine completed successfully.

NAME

       MPI_Info_create -  Creates a new info object

SYNOPSIS

       int MPI_Info_create( MPI_Info *info )
