XmClipboardCopy(3X)           SDK X11 R4.11MU05          XmClipboardCopy(3X)


NAME
       XmClipboardCopy--A clipboard function that copies a data item to
       temporary storage for later copying to clipboard

SYNOPSIS
       #include <Xm/Xm.h>
       #include <Xm/CutPaste.h>

       int XmClipboardCopy (display, window, itemid, formatname,
                 buffer, length, privateid, dataid)
            Display    * display;
            Window     window;
            long       itemid;
            char       * formatname;
            XtPointer  buffer;
            unsigned longlength;
            long       privateid;
            long       * dataid;


DESCRIPTION
       XmClipboardCopy copies a data item to temporary storage.  The data
       item is moved from temporary storage to the clipboard data structure
       when a call to XmClipboardEndCopy is made.  Additional calls to
       XmClipboardCopy before a call to XmClipboardEndCopy add additional
       data item formats to the same data item or append data to an existing
       format.  Formats are described in the Inter-Client Communication
       Conventions Manual (ICCCM) as targets.

       NOTE:  Do not call XmClipboardCopy before a call to
       XmClipboardStartCopy has been made.  The latter function allocates
       temporary storage required by XmClipboardCopy.

       If the buffer argument is NULL, the data is considered to be passed
       by name.  When data that has been passed by name is later requested
       by another application, the application that owns the data receives a
       callback with a request for the data.  The application that owns the
       data must then transfer the data to the clipboard with the
       XmClipboardCopyByName function.  When a data item that was passed by
       name is deleted from the clipboard, the application that owns the
       data receives a callback stating that the data is no longer needed.

       For information on the callback function, see the callback argument
       description for XmClipboardStartCopy.


       display     Specifies a pointer to the Display structure that was
                   returned in a previous call to XOpenDisplay or XtDisplay.

       window      Specifies a widget's window ID that relates the
                   application window to the clipboard.  The widget's window
                   ID can be obtained by using XtWindow.  The same
                   application instance should pass the same window ID to
                   each of the clipboard functions that it calls.

       itemid     Specifies the number assigned to this data item.  This
                   number was returned by a previous call to
                   XmClipboardStartCopy.

       formatname Specifies the name of the format in which the data item
                   is stored on the clipboard.  Format is known as target in
                   the ICCCM.

       buffer      Specifies the buffer from which the clipboard copies the
                   data.

       length      Specifies the length of the data being copied to the
                   clipboard.

       privateid  Specifies the private data that the application wants to
                   store with the data item.

       dataid     Specifies an identifying number assigned to the data item
                   that uniquely identifies the data item and the format.
                   This argument is required only for data that is passed by
                   name.


RETURN VALUE
       ClipboardSuccess
                   The function is successful.

       ClipboardLocked
                   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.

       ClipboardFail
                   The function failed because XmClipboardStartCopy was not
                   called or because the data item contains too many
                   formats.
