Subject: arrays of fixed-length strings
In netcdf-4.0, I don't see how to create variables which are arrays of
strings with length > 1. I see how to create arrays of
single-characters, and arrays of variable-length strings, but not
strings of a specified length.
Am I missing something, or is this not supported by HDF5?
Yes, fixed-length arrays are supported in HDF5. You need to use
something like the following HDF5 calls:
tid = H5Tcopy(H5T_C_S1);
H5Tset_size(tid, <string length>);

Quincey: OK, thanks. Maybe Russ or Ed can tell me whether this is
possible in netcdf-4.0? Being limited to single character arrays in
netcdf-3 was one of things I really wanted netcdf-4 to overcome.
Variable length strings are nice, but they don't map well to commonly
used data structures (i.e. arrays) in fortran or python.
