Next Previous Contents . You cannot use IRQs or DMA directly from a user-mode process. You need to write a kernel driver; see The Linux Kernel Hacker's Guide for details and the kernel source code for examples. You can disable interrupts from within a user-mode program, though it can be dangerous (even kernel drivers do it for as short a time as possible). After calling iopl(3) , you can disable interrupts simply by calling asm("cli"); , and re-enable them with asm("sti"); . Next Previous Contents

... A widget is any GtkObject that derives from GtkWidget ; before reading this chapter, you should be familiar with the chapter called The GTK+ Object and Type System . ... You will also need to know something about GDK to write a widget; be sure to skim the chapter called GDK Basics if you haven't. Widgets are easy to create; you only need to cut-and-paste the usual GtkObject boilerplate (instance and class initializers, a get_type() function, and so on), and then implement your widget's functionality...

... The previous example, Chapter 12, "Expanding Colored Squares Example," illustrates how to expand and contract the clipping region of a layer without changing the wrapping width of the layer.

... It is not always necessary to write a device driver for a device, especially in applications where no two applications will compete for the device. ... If your process is running as superuser (root), you can use the mmap() call to map some of your process memory to actual memory locations, by mmap() 'ing a section of /dev/mem. ...
