Hi,
I'm trying to write a wrapper for H5TB and pfb the code. I'm able to call
H5TBmake_table but getting a -1 as the result everytime :(. Any help is
appreciated !
C++ :
Definition :
[DllImport("hdf5_hldll.dll",
CharSet=CharSet::Auto,
CallingConvention=CallingConvention::StdCall)]
extern "C"
herr_t _cdecl H5TBmake_table( [MarshalAs(UnmanagedType::LPStr)]
String^ table_title,
hid_t loc_id,
[MarshalAs(UnmanagedType::LPStr)]
String^ dset_name,
hsize_t nfields,
const hsize_t nrecords,
size_t type_size,
[MarshalAs(UnmanagedType::LPArray, ArraySubType=UnmanagedType::LPStr)]
cli::array<String^>^
field_names,
[MarshalAs(UnmanagedType::LPArray)]
array<hsize_t>^ field_offset,
[MarshalAs(UnmanagedType::LPArray)]
array<hid_t>^ field_types,
hsize_t chunk_size,
void *fill_data,
int compress,
const void *data );
Signature definition :
namespace HDF5DotNet
{
generic <class Type>
herr_t H5TB::MakeTable(
String^ title,
H5LocId^ locId,
String^ datasetName,
hsize_t fieldsCount,
hsize_t recordsCount,
size_t typeSize,
array<String^>^ fieldNames,
array<hsize_t>^ fieldOffsets,
array<hid_t>^ fieldTypes,
hsize_t chunkSize,
H5Array<Type>^ fillData,
int compress,
H5Array<Type>^ data
);
}
Implementation :
namespace HDF5DotNet
{
generic <class Type>
herr_t H5TB::MakeTable(
String^ title,
H5LocId^ locId,
String^ datasetName,
hsize_t fieldsCount,
hsize_t recordsCount,
size_t typeSize,
array<String^>^ fieldNames,
array<hsize_t>^ fieldOffsets,
array<hid_t>^ fieldTypes,
hsize_t chunkSize,
H5Array<Type>^ fillData,
int compress,
H5Array<Type>^ data
)
{
pin_ptr<Type> _pin_fillData = fillData->getDataAddress();
void* _fillData = _pin_fillData ;
pin_ptr<Type> _pin_Data = data->getDataAddress();
void* _data = _pin_Data;
for(int i = 0; i < fieldNames->Length; i++)
Console::WriteLine( fieldNames[0]->ToString() +
"------" );
herr_t err = H5TBmake_table( title, locId->Id, datasetName,
fieldsCount, recordsCount, typeSize,
fieldNames, fieldOffsets, fieldTypes, chunkSize,
fillData, compress, data );
if( err < 0 )
Console::WriteLine("Failed creating table");
return err;
}
}
Kindly let me know where am I going wrong
Thanks & Regards
