I try to read a string attribute from a dataset.
Here is a code snippet:
var version int64 versionAttr, _ := dset.OpenAttribute("version") versionAttr.Read(&version, hdf5.T_STD_U64LE) fmt.Println(version) var start string startAttr, _ := dset.OpenAttribute("start") startAttr.Read(&start, hdf5.T_GO_STRING) fmt.Println(start)
Reading the version attribute is fine. Reading the 'start' attribute results in empty string. Here the snippet from h5dump:
ATTRIBUTE "start" { DATATYPE H5T_STRING { STRSIZE H5T_VARIABLE; STRPAD H5T_STR_NULLTERM; CSET H5T_CSET_UTF8; CTYPE H5T_C_S1; } DATASPACE SCALAR DATA { (0): "2018-09-04T02:27:43" } } ATTRIBUTE "version" { DATATYPE H5T_STD_I64LE DATASPACE SCALAR DATA { (0): 1 } }
I am excepting a variable start with this content "2018-09-04T02:27:43".
go: hdf5: master (c257073619f4b73c4c9da6318870d2ed0ca376ef)
Problem occurs either with libhdf5: 1.8.20 and libhdf5: 1.10.2
yes.
