I'm trying to modify the value of a dataset in a HDF5 file. In HDFView, the
type of this dataset is : String, length =variable, 1
This is the code C# I used :
//------------------------------
H5FileId oFileId = H5F.open(@"C:\test\TestVL.h5", H5F.OpenMode.ACC_RDWR);
H5DataSetId oDataSetId = H5D.open(oFileId, "DatasetName");
Encoding m_oEncoder = Encoding.GetEncoding("ISO-8859-1");
byte[] tBuffer = m_oEncoder.GetBytes("string to write");
H5DataTypeId oDataTypeId = H5D.getType(oDataSetId);
hvl_t[] vlArray = new hvl_t[1];
unsafe
{
vlArray[0].p = H5CrtHeap.Allocate(new IntPtr(size * sizeof(byte))).ToPointer();
vlArray[0].len = (ulong)(size * sizeof(byte));
for (int i = 0; i < size; i++)
{
((byte*)vlArray[0].p)[i] = tBuffer[i];
}
}
H5D.write(oDataSetId, oDataTypeId, new H5Array<hvl_t>(vlArray));
//------------------------------
The instruction HD5.write throw an "AccessViolationException" exception and I
don't see why ?
If you can help me,
Regards
Stéphane.
