C++ (Cpp) nsRefPtr::AddRef Examples

Example #1

File: ThebesLayerD3D9.cpp Project: mxOBS/deb-pkg_icedove

void
OpaqueRenderer::End()
{
  mSurface = nullptr;
  // gfxWindowsSurface returned from ::Begin() should be released before the
  // texture is used. This will assert that this is the case
#if 1
  if (mD3D9ThebesSurface) {
    mD3D9ThebesSurface->AddRef();
    nsrefcnt c = mD3D9ThebesSurface->Release();
    if (c != 1)
      NS_RUNTIMEABORT("Reference mD3D9ThebesSurface must be released by caller of Begin() before calling End()");
  }
#endif
  mD3D9ThebesSurface = nullptr;

}

Example #2
