A clipboard function that locks the clipboard
#include <Xm/CutPaste.h> int XmClipboardLock ( display, window) Display * display; Window window; (VOID)
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.
XmClipboardEndCopy (3), XmClipboardEndRetrieve (3), XmClipboardStartCopy (3), XmClipboardStartRetrieve (3), and XmClipboardUnlock (3).
