EGL绘制是否支持多线程？如何在多线程的场景下同时操作一块buffer进行图形绘制

void CreateShareEglContext() 
{ 
  if (renderContext == nullptr) { // renderContext是主线程context 
    RS_LOGE("renderContext_ is nullptr"); 
    return; 
  } 
  eglShareContext = renderContext->CreateShareContext(); //  创建share context 
  if (eglShareContext == EGL_NO_CONTEXT) { 
    RS_LOGE("eglShareContext is EGL_NO_CONTEXT"); 
    return; 
  } 
  if (!eglMakeCurrent(renderContext->GetEGLDisplay(), EGL_NO_SURFACE, EGL_NO_SURFACE, eglShareContext)) { 
    RS_LOGE("eglMakeCurrent failed"); 
    return; 
  } 
}
