ddi_regs_map_free(9F) Kernel Functions for Drivers ddi_regs_map_free(9F)NAME
ddi_regs_map_free - free a previously mapped register address space
SYNOPSIS
#include <sys/ddi.h>
#include <sys/sunddi.h>
void ddi_regs_map_free(ddi_acc_handle_t *handle);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI).
PARAMETERS
handle Pointer to a data access handle previously allocated by a call to a setup routine such as ddi_regs_map_setup(9F).
DESCRIPTION
ddi_regs_map_free() frees the mapping represented by the data access handle handle. This function is provided for drivers preparing to
detach themselves from the system, allowing them to release allocated system resources represented in the handle.
CONTEXT
ddi_regs_map_free() must be called from user or kernel context.

We have quite a few threads about this subject. I have collected some of them and arranged them by the OS which is primarily discussed in the thread. That is because the exact procedure depends on the OS involved. What's more, since you often need to interact with the boot process, the... (0 Replies)
I'm writing a command shell, and I want to be able to detect when the user presses an arrow key (otherwise it just prints [[A, [[B, etc.). I know it's relatively easy (although somewhat more time-consuming) to detect keystrokes in noncanonical mode, but I've noticed that the bash shell detects... (4 Replies)
I'm learning off Linux (Ubuntu) right now. I want to move up to Unix, but I don't want to rush like I did when it came to Windows --> to Linux. What is the best Unix OS that fits in pretty well with Ubuntu.
In other words is there kind of an equal Linux with Unix?
Also what do I need to... (10 Replies)
I noticed my hostname is <my-full-name>s-macbook.local. I'm not sure exactly what information leaves the local network, and whether the hostname is included, but if it is, this would mean people on the Internet can look at my hostname and see who I am. Before anyone says that's not possible,... (4 Replies)
