XmClipboardLock -- A clipboard function that locks the clipboard
int XmClipboardLock (display, window)
Display * display;
XmClipboardLock locks the clipboard from access by another application until XmClipboard-
Unlock is called. All clipboard functions lock and unlock the clipboard to prevent simul-
taneous 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
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.
The function was successful.
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.
