This is currently achieved +using a fixed timeout of one second. + +The XWin(1) server should indicate somehow (by placing an atom on the root window?) that it is running with it's +internal clipboard integration enabled, and xwinclip should notice this and exit with an appropriate error. + +Probably many other bugs. + +.SH "CONFORMING TO" +ICCCM (Inter-Client Communication Conventions Manual) 2.0 + +.SH AUTHORS +Contributors to xwinclip include Benjamin Riefenstahl, Roland Cassard, Brian Genisio, Colin Harrison, +Harold L Hunt II, Matsuzaki Kensuke, Jon Turney, Chris Twiner and Jeremy Wilkins. diff --git a/xorg-server/hw/xwin/winclipboardinit.c b/xorg-server/hw/xwin/winclipboardinit.c index 157006dab..8aef8fe02 100644 --- a/xorg-server/hw/xwin/winclipboardinit.c +++ b/xorg-server/hw/xwin/winclipboardinit.c @@ -31,25 +31,79 @@ #ifdef HAVE_XWIN_CONFIG_H #include <xwin-config.h> #endif -#include "dixstruct.h" -#include "winclipboard.h" + +#include <unistd.h> +#include <pthread.h> + +#include "win.h" +#include "winclipboard/winclipboard.h" +#include "windisplay.h" + +#define WIN_CLIPBOARD_RETRIES 40 +#define WIN_CLIPBOARD_DELAY 1 /* - * Local typedefs + * Local variables */ -typedef int (*winDispatchProcPtr) (ClientPtr); - -int winProcSetSelectionOwner(ClientPtr /* client */ ); +static pthread_t g_ptClipboardProc; /* - * References to external symbols + * */ +static void * +winClipboardThreadProc(void *arg) +{ + char szDisplay[512]; + int clipboardRestarts = 0; + + while (1) + { + Bool fShutdown; + + ++clipboardRestarts; -extern pthread_t g_ptClipboardProc; -extern winDispatchProcPtr winProcSetSelectionOwnerOrig; -extern Bool g_fClipboard; -extern HWND g_hwndClipboard; + /* Use our generated cookie for authentication */ + winSetAuthorization(); + + /* Setup the display connection string */ + /* + * NOTE: Always connect to screen 0 since we require that screen + * numbers start at 0 and increase without gaps.
