MPI_File_get_amode - Returns access mode associated with an open file.

  #include <mpi.h>
  int MPI_File_get_amode(MPI_File fh, int *amode)

  USE MPI
  ! or the older form: INCLUDE 'mpif.h'
  MPI_FILE_GET_AMODE(FH, AMODE, IERROR)
  	INTEGER	FH, AMODE, IERROR

  USE mpi_f08
  MPI_File_get_amode(fh, amode, ierror)
  	TYPE(MPI_File), INTENT(IN) :: fh
  	INTEGER, INTENT(OUT) :: amode
  	INTEGER, OPTIONAL, INTENT(OUT) :: ierror

  #include <mpi.h>
  int MPI::File::Get_amode() const

fh

File handle (handle).

amode

File access mode used to open the file (integer).

IERROR

Fortran only: Error status (integer).

MPI_File_get_amode returns, in amode, the access mode associated with the open file fh.

Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ functions do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism will be used to throw an MPI::Exception object.

Before the error value is returned, the current MPI error handler is called. For MPI I/O function errors, the default error handler is set to MPI_ERRORS_RETURN. The error handler may be changed with MPI_File_set_errhandler; the predefined error handler MPI_ERRORS_ARE_FATAL may be used to make I/O errors fatal. Note that MPI does not guarantee that an MPI program can continue past an error.
