You can pass it to any function in the MSI SDK through ctypes.
e.g.
def ReadStream(record, field):
buf = (ctypes.c_char * 2048)()
orig_size = ctypes.sizeof(buf)
status = 0
res = []
while status == 0:
size = ctypes.c_long(ctypes.sizeof(buf))
status = msidll.MsiRecordReadStream(
record.hanlde, field, ctypes.byref(buf), ctypes.byref(size))
res.append(buf.raw)
if size.value != orig_size:
break
data = "".join(res)
return data
or any of the other functions not currently implemented in _msi.c
Some of the other important ones (to me at least) are:
- MsiDatabaseGetPrimaryKeys
- MsiDatabaseExport
- MsiDatabaseImport
If the whole MSI SDK is wrapped - then exposing the handles would have no use
:).
The alternative I have so far is to re-write _msi.c using ctypes (already
done), but I thought it would be better if not all of _msi.c had to be
re-implemented.
One alternative patch is to include those extra functions in _msi.c (though I
am not sure I have the C skills to achieve that easily - and it may still miss
functionality, and it may have even less chance of being accepted)
