XmClipboardRetrieve - A clipboard function that retrieves
a data item from the clipboard
#include <Xm/Xm.h> #include <Xm/CutPaste.h>
int XmClipboardRetrieve (display, window, format_name,
buffer, length, num_bytes, private_id)
Display * display;
Window window;
char * format_name;
XtPointer buffer;
unsigned long length;
unsigned long * num_bytes;
long * private_id;
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.
Specifies a pointer to the Display structure that
was returned in a previous call to XOpenDisplay or XtDisplay.
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. Specifies the name of
a format in which the data is stored on the clipboard.
Specifies the buffer to which the application wants the
clipboard to copy the data. Specifies the length of the
application buffer. Specifies the number of bytes of data
copied into the application buffer. 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.
The function is 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. The data
returned is truncated because the user did not provide a
buffer large enough to hold the data. 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.
