SYNOPSIS

Display * display;
Window window;
int * count;

DESCRIPTION
XmClipboardInquireCount returns the number of data item
formats available for the data item in the clipboard. This
function also returns the maximum name length for all
formats in which the data item is stored.
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.
count Returns the number of data item formats
available for the data item in the
clipboard. If no formats are available,
this argument equals zero. The count
includes the formats that were passed by
name.
max_format_name_length
Specifies the maximum length of all format
names for the data item in the clipboard.
RETURN VALUE
ClipboardSuccessThe 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.
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.
