Schindelin) - * x0rfbserver, the original native X vnc server (Jens Wagner) - * krfb, the KDE desktopsharing project (Tim Jansen) - * - * Please see http://www.karlrunge.com/x11vnc for the most up-to-date - * information about x11vnc. Some of the following text may be out - * of date. - * - * The primary goal of this program is to create a portable and simple - * command-line server utility that allows a VNC viewer to connect - * to an actual X display (as the above do). The only non-standard - * dependency of this program is the static library libvncserver.a. - * Although in some environments libjpeg.so or libz.so may not be - * readily available and needs to be installed, they may be found - * at ftp://ftp.uu.net/graphics/jpeg/ and http://www.gzip.org/zlib/, - * respectively. To increase portability it is written in plain C. - * - * Another goal is to improve performance and interactive response. - * The algorithm of x0rfbserver was used as a base. Many additional - * heuristics are also applied. - * - * Another goal is to add many features that enable and incourage creative - * usage and application of the tool. Apologies for the large number - * of options! - * - * To build: - * - * Obtain the libvncserver package (http://libvncserver.sourceforge.net). - * As of 12/2002 this version of x11vnc.c is contained in the libvncserver - * CVS tree and released in version 0.5. - * - * gcc should be used on all platforms. To build a threaded version put - * "-D_REENTRANT -DX11VNC_THREADED" in the environment variable CFLAGS - * or CPPFLAGS (e.g. before running the libvncserver configure). The - * threaded mode is a bit more responsive, but can be unstable (e.g. - * if more than one client the same tight or zrle encoding). - * - * Known shortcomings: - * - * The screen updates are good, but of course not perfect since the X - * display must be continuously polled and read for changes and this is - * slow for most hardware. This can be contrasted with receiving a change - * callback from the X server, if that were generally possible... (UPDATE: - * this is handled now with the X DAMAGE extension, but unfortunately - * that doesn't seem to address the slow read from the video h/w). So, - * e.g., opaque moves and similar window activity can be very painful; - * one has to modify one's behavior a bit. - * - * General audio at the remote display is lost unless one separately - * sets up some audio side-channel such as esd. - * - * It does not appear possible to query the X server for the current - * cursor shape. We can use XTest to compare cursor to current window's - * cursor, but we cannot extract what the cursor is... (UPDATE: we now - * use XFIXES extension for this. Also on Solaris and IRIX Overlay - * extensions exists that allow drawing the mouse into the framebuffer) - * - * The current *position* of the remote X mouse pointer is shown with - * the -cursor option. Further, if -cursor X is used, a trick - * is done to at least show the root window cursor vs non-root cursor. - * (perhaps some heuristic can be done to further distinguish cases..., - * currently "-cursor some" is a first hack at this) - * - * Under XFIXES mode for showing the cursor shape, the cursor may be - * poorly approximated if it has transparency (alpha channel). - * - * Windows using visuals other than the default X visual may have - * their colors messed up. When using 8bpp indexed color, the colormap - * is attempted to be followed, but may become out of date. Use the - * -flashcmap option to have colormap flashing as the pointer moves - * windows with private colormaps (slow). Displays with mixed depth 8 and - * 24 visuals will incorrectly display windows using the non-default one. - * On Sun and Sgi hardware we can to work around this with -overlay. - * - * Feature -id <windowid> can be picky: it can crash for things like - * the window not sufficiently mapped into server memory, etc (UPDATE: - * we now use the -xrandr mechanisms to trap errors more robustly for - * this mode). SaveUnders menus, popups, etc will not be seen. - * - * Under some situations the keysym unmapping is not correct, especially - * if the two keyboards correspond to different languages. The -modtweak - * option is the default and corrects most problems. One can use the - * -xkb option to try to use the XKEYBOARD extension to clear up any - * remaining problems. - * - * Occasionally, a few tile updates can be missed leaving a patch of - * color that needs to be refreshed. This may only be when threaded, - * which is no longer the default. - * - * There seems to be a serious bug with simultaneous clients when - * threaded, currently the only workaround in this case is -nothreads - * (which is now the default). - */ - - -/* -- x11vnc.c -- */ - -#include "x11vnc.h" -#include "xwrappers.h" -#include "xdamage.h" -#include "xrecord.h" -#include "xevents.h" -#include "xinerama.h" -#include "xrandr.h" -#include "xkb_bell.h" -#include "win_utils.h" -#include "remote.h" -#include "scan.h" -#include "gui.h" -#include "help.h" -#include "user.h" -#include "cleanup.h" -#include "keyboard.h" -#include "pointer.h" -#include "cursor.h" -#include "userinput.h" -#include "screen.h" -#include "connections.h" -#include "rates.h" -#include "unixpw.h" -#include "inet.h" -#include "sslcmds.h" -#include "sslhelper.h" -#include "selection.h" -#include "pm.h" -#include "solid.h" - -/* - * main routine for the x11vnc program - */ -void watch_loop(void);
