Trouble Read Fixed Length Strings


#1

Hi,

I’m brand new to using the HDF5 library and I’m having trouble trying to read some fixed length strings from an HDF5 file that was given to me. I am able to read the variable length strings.

The variable length strings have this format:
DATATYPE H5T_STRING {
STRSIZE H5T_VARIABLE;
STRPAD H5T_STR_NULLTERM;
CSET H5T_CSET_UTF8;
CTYPE H5T_C_S1;
}
DATASPACE SIMPLE { ( 24 ) / ( 24 ) }
DATA {
(0): “Cut_1”, “Cut_2”, “Cut_3”, “Cut_4”, “Cut_5”, “Cut_6”, “Cut_7”,
(7): “Cut_8”, “Cut_9”, “Cut_10”, “Cut_11”, “Cut_12”, “Cut_13”,
(13): “Cut_14”, “Cut_15”, “Cut_16”, “Cut_17”, “Cut_18”, “Cut_19”,
(19): “Cut_20”, “Cut_21”, “Cut_22”, “Cut_23”, “Cut_24”
}

and I use this code to read the array of strings:
/*
* Open file
*/
file = H5Fopen (FILE, H5F_ACC_RDONLY, H5P_DEFAULT);
dset = H5Dopen(loc_id, name, H5P_DEFAULT);
datatype = H5Dget_type(dset);
