Expand description

§Parameters

  • attr: an SDL_GLAttr enum value specifying the OpenGL attribute to set.
  • value: the desired value for the attribute.

§Return value

Returns true on success or false on failure; call SDL_GetError() for more information.

§Thread safety

This function should only be called on the main thread.

§Availability

This function is available since SDL 3.2.0.
