sdlGlSetAttribute function video

bool sdlGlSetAttribute(
  1. int attr,
  2. int value
)

Set an OpenGL window attribute before window creation.

This function sets the OpenGL attribute attr to value. The requested attributes should be set before creating an OpenGL window. You should use SDL_GL_GetAttribute() to check the values after creating the OpenGL context, since the values obtained can differ from the requested ones.

\param attr an enum value specifying the OpenGL attribute to set. \param value the desired value for the attribute. \returns true on success or false on failure; call SDL_GetError() for more information.

\threadsafety This function should only be called on the main thread.

\since This function is available since SDL 3.2.0.
