Syntax

#include <Xm/Xm.h>

int XmClipboardInquireFormat (display, window, index, format_name_buf,
			      buffer_len, copied_len)
Display * display;
Window window;
int index;
XtPointer format_name_buf;
unsigned long buffer_len;
unsigned long * copied_len;

Description

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.

index

Specifies which of the ordered format names to obtain. If this index is greater than the number of formats for the data item, this function returns a zero in the copied_len argument.

format_name_buf

Specifies the buffer that receives the format name.

buffer_len

Specifies the number of bytes in the format name buffer.

copied_len

Specifies the number of bytes in the string copied to the buffer. If this argument equals zero, there is no nth format for the data item.

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.
