◆ WindowsLink()

void BURGER_API Burger::DisplayOpenGL::WindowsLink ( void )

static

Manually load in all the OpenGL extensions.

Windows doesn't automatically link in all of the OpenGL functions when opengl32.lib is linked in. The extensions need to be manually loaded via calls to wglGetProcAddress() after an OpenGL pixelformat is selected.

Call this function immediately after an OpenGL pixelformat is selected and then all of the OpenGL extended function will "magically" appear and work as if they were directly linked in.

Note: This is only available on Windows

◆ WindowsUnlink()

void BURGER_API Burger::DisplayOpenGL::WindowsUnlink ( void )

static

Release all of the OpenGL extensions.

When an OpenGL pixelformat is released, call this function to prevent accidental calling of any OpenGL functions that are connected to a disabled device driver.

Note: This is only available on Windows
