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.

irframe -- IrDA frame level driver
SYNOPSIS
irframe* at oboe?
irframe* at uirda?
irframe* at ustir?
pseudo-device irframetty
#include <dev/irdaio.h>
DESCRIPTION
The irframe driver provides support for IrDA frame level transmission. It does not contain the IrDA protocol stack per se, but the stack can
be built on top of the irframe driver.
Access to frames is via the read(2) and write(2) system calls. Each write constitutes one frame, and each read yields one frame. The
poll(2) system call can be used to check for availability of frames. There are also a number of ioctl(2) calls to manipulate the device:
IRDA_RESET_PARAMS
Reset the parameters set by IRDA_SET_PARAMS.
IRDA_SET_PARAMS (struct irda_params)
Set the speed, extra beginning of frame bytes, and maximum frame size.
IRDA_GET_SPEEDMASK (int)
Get the set of allowable speeds.
IRDA_GET_TURNAROUNDMASK (int)
Get the set of allowable turn around times.

HISTORY
The irframe driver appeared in NetBSD 1.6.
