C-- File dfile.F: Routines that handle actual I/O |

C-- to model "dump" files. |
| 7 |
C-- These low-level routines could be replaced |
| 8 |
C-- by platform/environment specific C or |
| 9 |
C-- MPI-2 routines one day! In some situations the |
| 10 |
C-- functionality of these low-level routines is |
| 11 |
C-- encompassed by the data handling package. For |
| 12 |
C-- example netCDF provides primitive that are |

C-- Contents |
| 15 |
C-- DFILE_CLOSE - Closes dump file |
| 16 |
C-- DFILE_INIT - Initialisation procedure for subsequent DFILE |
| 17 |
C data-structures. Only called once per run. |
| 18 |
C-- DFILE_OPEN - Opens dump file |
| 19 |
C-- DFILE_READ_R8 - Reads from a dump file |
| 20 |
C-- DFILE_READ_R4 - Reads from a dump file |
| 21 |
C-- DFILE_SET_RO - Sets new connections to be read-only |
| 22 |
C-- DFILE_SET_RW - Sets new connections to be read-write |
| 23 |
C-- DFILE_SET_STOP_ON_ERROR - Sets new connections to STOP on error |
| 24 |
C-- DFILE_SET_CONT_ON_ERROR - Sets new connections to continue |

C on error |
| 26 |
C-- DFILE_WRITE_R4 - Writes to a dump file |

C Notes: |
| 30 |
C ====== |
| 31 |
C The default behaviour is for the model to stop if an |
| 32 |
C input errors occur but to continue if output errors occur. |
| 33 |
C However, this policy is not enforced in these low-level routines. |
| 34 |
C Instead these routines are coded to allow either continue |
| 35 |
C on error or stop on error. Which action is taken |
| 36 |
C is controlled via a mode flag which is set from the higher |
| 37 |
C level calls to these routines. A mode flag is also used to |
| 38 |
C control whether the DFILE_OPEN routine opens a file in |
| 39 |
C read-write or read-only mode. On some systems this is necessary |
| 40 |
C as the default is read-write and will fail for read-only files or |
| 41 |
C file systems. Other systems don't support the OPEN(...='READ_ONLY') |
| 42 |
C so this feature may need to be switched on or off as appropriate. |
| 43 |
C The DFILE_SET routines provide this mechanism. They work by setting |
| 44 |
C a "context" flag which is applied to IO ahndles when the DFILE_OPEN |
| 45 |
C call is made. IO handles that are already open are not affected by |
| 46 |
C subsequent calls to DFILE_SET routines. |
