NAME
       MPI_File_get_errhandler -  Get the error handler attached to a file

SYNOPSIS
       int MPI_File_get_errhandler(MPI_File file, MPI_Errhandler *errhandler)

INPUT PARAMETERS
       file   - MPI file (handle)


OUTPUT PARAMETERS
       errhandler
              - handler currently associated with file (handle)



THREAD AND INTERRUPT SAFETY
       This routine is thread and interrupt safe only if no MPI routine that
       updates or frees the same MPI object may be called concurrently with
       this routine.

       The MPI standard defined a thread-safe interface but this does not mean
       that all routines may be called without any thread locks.  For example,
       two threads must not attempt to change the contents of the same
       MPI_Info object concurrently.  The user is responsible in this case for
       using some mechanism, such as thread locks, to ensure that only one
       thread at a time makes use of this routine.



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.
