XmClipboardRetrieve(3X) SDK X11 R4.11MU05 XmClipboardRetrieve(3X)
NAME
XmClipboardRetrieve--A clipboard function that retrieves a data item
from the clipboard
SYNOPSIS
#include <Xm/Xm.h>
#include <Xm/CutPaste.h>
int XmClipboardRetrieve (display, window, formatname,
buffer, length, numbytes, privateid)
Display * display;
Window window;
char * formatname;
XtPointer buffer;
unsigned longlength;
unsigned long* numbytes;
long * privateid;
DESCRIPTION
XmClipboardRetrieve retrieves the current data item from clipboard
storage. It returns a warning if the clipboard is locked; if there
is no data on the clipboard; or if the data needs to be truncated
because the buffer length is too short.
Between a call to XmClipboardStartRetrieve and a call to
XmClipboardEndRetrieve, multiple calls to XmClipboardRetrieve with
the same format name result in data being incrementally copied from
the clipboard until the data in that format has all been copied.
The return value ClipboardTruncate from calls to XmClipboardRetrieve
indicates that more data remains to be copied in the given format.
It is recommended that any calls to the Inquire functions that the
application needs to make to effect the copy from the clipboard be
made between the call to XmClipboardStartRetrieve and the first call
to XmClipboardRetrieve. That way, the application does not need to
call XmClipboardLock and XmClipboardUnlock.
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.
formatname Specifies the name of a format in which the data is
stored on the clipboard.
buffer Specifies the buffer to which the application wants the
clipboard to copy the data.
length Specifies the length of the application buffer.
numbytes Specifies the number of bytes of data copied into the
application buffer.
privateid Specifies the private data stored with the data item by
the application that placed the data item on the
clipboard. If the application did not store private data
with the data item, this argument returns zero.
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.
ClipboardTruncate
The data returned is truncated because the user did not
provide a buffer large enough to hold the data.
ClipboardNoData
The function could not find data on the clipboard
corresponding to the format requested. This could occur
because the clipboard is empty; there is data on the
clipboard but not in the requested format; or the data in
the requested format was passed by name and is no longer
available.
