Chapter 2: Display Functions

Before your program can use a display, you must establish a connection to the X server. Once you have established a connection, you then can use the Xlib macros and functions discussed in this chapter to return information about the display. This chapter discusses how to:

• Open (connect to) the display

• Obtain information about the display, image format, and screen

• Free client-created data

• Close (disconnect from) a display

The chapter concludes with a general discussion of what occurs when the connection to the X server is closed.
