Function CVOpenGLBufferAttach 

pub unsafe extern "C-unwind" fn CVOpenGLBufferAttach(
    open_gl_buffer: &CVOpenGLBuffer,
    cgl_context: CGLContextObj,
    face: u32,
    level: i32,
    screen: i32,
) -> CVReturn

👎Deprecated: OpenGL/OpenGLES is no longer supported. Use Metal APIs instead. (Define COREVIDEO_SILENCE_GL_DEPRECATION to silence these warnings)

Available on crate feature CVBuffer and crate feature CVImageBuffer and crate feature CVOpenGLBuffer and crate feature CVReturn and crate feature objc2-open-gl and macOS only.

Parameter openGLBuffer: The buffer you wish to attach a GL context to

Parameter cglContext: The CGLContextObj you wish to attach

Parameter face: The target GL face enum (0 for non cube maps)

Parameter level: The mipmap level index you wish to attach to

Parameter screen: The virtual screen number you want to use

Returns: kCVReturnSuccess if the attachment succeeded

Safety

cgl_context must be a valid pointer.
