IDiaSession::getFuncMDTokenMap

  • Article

Retrieves the contents of the .NET Native metadata function token map.

Syntax

HRESULT getFuncMDTokenMap(
    DWORD cb,
    DWORD *pcb,
    BYTE *pb
);

Parameters

cb

[in] The size in bytes of the buffer pointed to by pb for receiving the .NET Native metadata function token map.

pcb

[out] Returns the size in bytes of the .NET Native metadata function token map (that is, the number of bytes written into pb).

pb

[out] Buffer to receive the contents of the .NET Native metadata function token map. This must be at least cb bytes in size.

Return Value

If successful, returns S_OK; otherwise, returns an error code.

Example

This shows how to retrieve the size of the map and then retrieve the full token map.

DWORD size = 0;
HRESULT hr = pDiaSession->getFuncMDTokenMapSize(&size);
if (FAILED(hr)) {
   return hr;
}
if (size == 0) {
   return S_FALSE;
}

BYTE * map = new (std::nothrow) BYTE[size];
if (map == nullptr) {
   return E_OUTOFMEMORY;
}

hr = pDiaSession->getFuncMDTokenMap(size, &size, map);
if (FAILED(hr)) {
   delete [] map;
   return hr;
}
