8.2.12 X Record Extension The purpose of this extension is to support the recording and reporting of all core X protocol and arbitrary X extension protocol. The extension is used to record the core X protocol and arbitrary X extension protocol entirely within the X server itself. When the extension has been requested to record specific protocol by one or more recording clients, the protocol data is formatted and returned to the recording clients. The extension provides a mechanism for capturing all events, including input device events that do not go to any clients. 8.2.13 ICE X Rendezvous The Inter-Client Exchange protocol (ICE) that became a standard in X11R6 specifies a generic communication framework for data exchange between arbitrary clients. The ICE protocol itself does not specify the manner in which two clients interested in communicating using ICE are made aware of each other’s existence. The ICE X Rendezvous protocol is one standard protocol by which two clients who have connections to a common X server can rendezvous. This new protocol is included in the ICE Protocol Specification document. 8.2.14 Print Extension The print extension supports output to hardcopy devices using the core X drawing requests. The print extension adds requests for job and page control and defines how specific printer attributes are communicated between the server and printing clients. Printer attribute specifications are modeled after the ISO 10175 specification. An X Client that wants to produce hardcopy output will typically open a second connection to an X print server, produce a print job, and then close the print server connection. The print server may be the same process as the display server (the term video server is sometimes used), although the implementation provided in R6.2 does not completely support video and print servers in the same binary. 8.2.14.1 Running an X Print Server The print server is simply an X-server with the print extension and special DDX implementations. The X print server is started like any other X-server. The following command line is an example for use with a typical configuration: # Xprt :1 -ac The options used in the example are: :1 On a host that is running a video display server you will need to specify a different display from the default. -ac Disable access control since no simple mechanism for sharing keys is provided. The X print server also supports the following additional options: -XpFile Points to the directory containing the print server configuration files. 200 AIX Version 4.3 Differences Guide
XPCONFIGDIR Environment variable specifying alternative location of the print server configuration files. The print server is configured through a directory of configuration files that define printer model types and instances of printer models. An example configuration tree is provided. By convention, clients locate the print server using the environment variable XPRINTER. The syntax of XPRINTER is an augmented DISPLAY: printerName@host:display where printerName is one of the printer instances listed in the print server configuration files. The use of XPRINTER, and its syntax, is an application convention only; there is nothing in the supplied libraries that uses (or parses) this environment variable. 8.2.15 Xlib Vertical Writing and User-Defined Characters The Xlib output method implementation has been enhanced to support the XOM drawing direction XOMOrientation_TTB_RTL. Vertical writing information, and other locale specific information, is read from the file /%L/XLC_LOCALE. The X[mb|wc]TextEscapement functions now return the text escapement in pixels for the vertical or horizontal direction depending on the XNOrientation XOCValue. The X[mb|wc]DrawString functions will now render a character string in the vertical or horizontal direction depending on the XNOrientation XOCValue. The Xlib NLS database implementation has been enhanced to support extended segments used for interchanging non-standard code sets. Support has been added for control sequences and encoding names used in extended segments and conversion of glyph indexes when interchanging data in extended segments. 8.2.16 Xlib Library Xlib now supports multi-threaded access to a single display connection. Xlib functions lock the display structure, causing other threads calling Xlib functions to be suspended until the first thread unlocks. Threads inside Xlib waiting to read to or write from the X-server do not keep the display locked, so, for example, a thread hanging on XNextEvent() will not prevent other threads from doing output to the server. The display and GC structures have been made opaque to normal application code; references to private fields will get compiler errors. You can work around some of these by compiling with -DXLIB_ILLEGAL_ACCESS, but it is better to fix the offending code. The Xlib implementation has been changed to support a form of asynchronous replies, meaning that a request can be sent to the server, and then other requests can be generated without waiting for the first reply to come back. This is used to an advantage in two new functions, XInternAtoms() and XGetAtomNames(), which reduce what would otherwise require multiple round trips to the server Graphical Environment Enhancements 201
