NAME
XmClipboardRetrieve -- A clipboard function that retrieves a data item
from the clipboard
SYNOPSIS
#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;
(void)
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 XmClipboardEn-
dRetrieve, 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 XmClipboardTruncate 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 appli-
cation needs to make to effect the copy from the clipboard be made
between the call to XmClipboardStartRetrieve and the first call to
XmClipboardRetrieve. This 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 the window ID of a widget that relates the applica-
tion 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 func-
tions that it calls.
format_name
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 clip-
board to copy the data. The function allocates space to hold
the data returned into the buffer. The application is
responsible for managing this allocated space. The applica-
tion can recover this allocated space by calling XtFree.
length Specifies the length of the application buffer.
num_bytes Specifies the number of bytes of data copied into the appli-
cation buffer.
private_id
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 0 (zero).
RETURN
XmClipboardSuccess
The function was successful.
XmClipboardLocked
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.
XmClipboardTruncate
The data returned is truncated because the user did not pro-
vide a buffer large enough to hold the data.
XmClipboardNoData
The function could not find data on the clipboard correspond-
ing 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.
