Hi Ed,H5Dvlen_reclaim is used to release memory allocated by library while reading variable-length data. You may use free function to deallocate array of char pointers, i.e.
for (i=0; i<N; i++) free read_txt[i]; or you may use H5Dvlen_reclaim (type_id, space_id, H5P_DEFAULT, read_txt)where type_id corresponds to the variable string datatypes and space_id corresponds to 1-DIM array of size N.
The name of the function is misleading. It should be probably H5Tvlen_reclaimIn the example I sent you yesterday, I used free function, since the attribute was just one string (not an array of strings and not a compound datatype that had string member).
