XmClipboardLock(library call) XmClipboardLock(library call)
NAME
XmClipboardLock -- A clipboard function that locks the clipboard
SYNOPSIS
#include <Xm/CutPaste.h>
int XmClipboardLock (display, window)
Display * display;
Window window;
(void)
DESCRIPTION
XmClipboardLock locks the clipboard from access by another application until XmClipboardUnlock is called. All clipboard functions lock and
unlock the clipboard to prevent simultaneous access. This function allows the application to keep the clipboard data from changing between
calls to Inquire and other clipboard functions. The application does not need to lock the clipboard between calls to XmClipboardStartCopy
and XmClipboardEndCopy or to XmClipboardStartRetrieve and XmClipboardEndRetrieve.
If the clipboard is already locked by another application, XmClipboardLock returns an error status. Multiple calls to this function by the
same application increase the lock level.
display Specifies a pointer to the Display structure that was returned in a previous call to XOpenDisplay or XtDisplay.
window Specifies the window ID of a widget that relates the application window to the clipboard. The widget's window ID can be obtained
through XtWindow. The same application instance should pass the same window ID to each of the clipboard functions that it calls.
RETURN
XmClipboardSuccess
The function was successful.
XmClipboardLocked
The function failed because the clipboard was locked by another application. The application can continue to call the function
again with the same parameters until the lock goes away. This gives the application the opportunity to ask if the user wants to
keep trying or to give up on the operation.
