UNREGISTER_FRAMEBUFF(9) 				       Frame Buffer Library					   UNREGISTER_FRAMEBUFF(9)

NAME
       unregister_framebuffer - releases a frame buffer device

SYNOPSIS
       int unregister_framebuffer(struct fb_info * fb_info);

ARGUMENTS
       fb_info
	   frame buffer info structure

DESCRIPTION
       Unregisters a frame buffer device fb_info.

       Returns negative errno on error, or zero for success.

       This function will also notify the framebuffer console to release the driver.

       This is meant to be called within a driver's module_exit function. If this is called outside module_exit, ensure that the driver implements
       fb_open and fb_release to check that no processes are using the device.
