| 6 | ! Three criticisms may be made about the Fortran 90 NetCDF interface: |
|---|
| 7 | |
|---|
| 8 | ! -- NetCDF procedures are usually functions with side effects. |
|---|
| 9 | ! First, they have "intent(out)" arguments. |
|---|
| 10 | ! Furthermore, there is obviously data transfer inside the procedures. |
|---|
| 11 | ! Any data transfer inside a function is considered as a side effect. |
|---|
| 12 | |
|---|
| 13 | ! -- The caller of a NetCDF procedure usually has to handle the error |
|---|
| 14 | ! status. NetCDF procedures would be much friendlier if they behaved |
|---|
| 15 | ! like the Fortran input/output statements. That is, the error status |
|---|
| 16 | ! should be an optional output argument. |
|---|
| 17 | ! If the caller does not request the error status and there is an |
|---|
| 18 | ! error then the NetCDF procedure should produce an error message |
|---|
| 19 | ! and stop the program. |
|---|
| 20 | |
|---|
| 21 | ! -- Some procedures use array arguments with assumed size. |
|---|
| 22 | ! It would be better to use the pointer attribute. |
|---|
| 23 | |
|---|
| 24 | ! This module produces a NetCDF interface that answers those three |
|---|
| 25 | ! criticisms for some (not all) procedures. |
|---|
| 26 | |
|---|
| 27 | ! "nf95_get_att" is more secure than "nf90_get_att" because it |
|---|
| 28 | ! checks that the "values" argument is long enough and removes the |
|---|
| 29 | ! null terminator, if any. |
|---|
| 30 | |
|---|
| 31 | ! This module replaces some of the official NetCDF procedures. |
|---|
| 32 | ! This module also provides the procedures "handle_err" and "nf95_gw_var". |
|---|
| 33 | |
|---|
| 34 | ! This module provides only a partial replacement for some generic |
|---|
| 35 | ! procedures such as "nf90_def_var". |
