The Linux kernel then associates those functions with the character device, so for example when a user-mode application calls the read() function on a character device file, it will result in a syscall and then the kernel will route this call to a read function specified when creating the driver. The Device Driver Source Code. The source code for the ebbchar device driver is provided in Listing 2. Similar to the code in the first article in this series, there is an init() function and an exit() function. However, there are additional file_operations functions that are required for the character device. Dev_open(): Called each time the device is opened from user space. Linux character device drivers development This intensive course transforms an IT-Professional or a Student into a Linux Device Driver & Kernel Developer for Character Storage devices, Block Storage devices & Network Storage devices and for those Programmers who already working on Linux, but looking for a methodical and concept clearing professional training on Linux system and kernel. Driver provides low level device functions devices are treated as files (/dev entries) character devices are sequential (read/write one byte at a time, in linear order). The Device Driver Source Code. The source code for the ebbchar device driver is provided in Listing 2. Similar to the code in the first article in this series, there is an init() function and an exit() function.
I'm looking for an exhaustive, university-level book or guide to study in order to gain the ability of writing Mac OS X device drivers. I'm totally ignorant on this OS, but I'm already skilled on Linux.

Is there any Mac OS X counterpart for book 'Linux Device Drivers'?
The best guide should introduce OS internals too, makes clear kernel space and userland differences and so on.
Thanks in advance

The Apple Developer Connection web site contains lots of documentation. There is a whole section on Hardware & Drivers here in particular a Getting Started document here. Probably the best overall introduction to OS X internals is Mac OS X Internals by Amit Singh.

Amit Singh's wonderful book Mac OS X Internals: A Systems Approach has an extensive section on kernel extensions, the IOKit and drivers. It's the best general resource on OS X internals that I know of, but it doesn't cover the latest system updates; it only covers up to the 10.4 release (Tiger).

Linux Character Device Driver For Mac
Amit Singh's book is good but as other posters noted it needs to be updated. I'm getting up to speed on IOKit and opted for another newer book OS X and iOS Kernel Programming. It doesn't have the depth of Singh's book but it has many practical examples of driver code. It is perhaps a better choice if you want get going quickly.

I suggest the following as it is updated to Snow Leopard and Lion: Mac OS X and iOS Internals: To the Apple's Core by Jonathon Levine: http://www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias%3Dstripbooks&field-keywords=Mac+internals&rh=n%3A283155%2Ck%3AMac+internals
This is quite a good book regarding all aspects of Mac OS X internals.
