XmClipboardRetrieve(3X) OSF/Motif XmClipboardRetrieve(3X)NAMEXmClipboardRetrieve - A clipboard function that retrieves a data item
from the clipboard
SYNOPSIS
#include <Xm/Xm.h> #include <Xm/CutPaste.h>
int XmClipboardRetrieve (display, window, format_name, buf‐
fer, length, num_bytes, private_id) Display * display;
Window window; char * format_name;
XtPointer buffer; unsigned longlength; unsigned long*
num_bytes; long * private_id;
DESCRIPTIONXmClipboardRetrieve 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 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 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. That way, the application does not need to call
XmClipboardLock and XmClipboardUnlock. Specifies a pointer to the Dis‐
play 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. Speci‐
fies 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.
RETURN VALUE
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 cor‐
responding to the format requested. This could occur because the clip‐
board 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.
