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;
char * format_name;
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
Specifies a pointer to the Display
structure that was returned in a previous call to XOpenDisplay
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
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
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.
