vlc_gl_surface_CheckSize()

bool vlc_gl_surface_CheckSize	(	vlc_gl_t *	gl,
		unsigned *restrict	width,
		unsigned *restrict	height
	)

Checks if the dimensions of the surface used by the OpenGL context have changed (since the previous call), and the OpenGL viewport should be updated.

Returns

true if at least one dimension has changed, false otherwise

Warning

This function is intrinsically race-prone. The dimensions can change asynchronously.
