示例#1

文件： glx.cpp 项目： NoSuchProcess/openswr

void glXDestroyContext(Display *pDisplay, GLXContext ctx)
{
    auto *pState = reinterpret_cast<OGL::State *>(ctx);

    if (contexts.find(pState) == currentContext)
    {
        currentContext = contexts.end();
    }

    contexts.erase(pState);

    OGL::Destroy(*pState);
    pState->~State();

    _aligned_free(pState);
}
