DESCRIPTION
The
XtConvert
function looks up the type converter registered to convert from_type
to to_type, computes any additional arguments needed, and then calls
XtDirectConvert.
XtConvert
has been replaced by
XtConvertAndStore.
The
XtDirectConvert
function looks in the converter cache to see if this conversion procedure
has been called with the specified arguments.
If so, it returns a descriptor for information stored in the cache;
otherwise, it calls the converter and enters the result in the cache.
Before calling the specified converter,
XtDirectConvert
sets the return value size to zero and the return value address to NULL.
To determine if the conversion was successful,
the client should check to_return.address for non-NULL.
XtDirectConvert
has been replaced by
XtCallConverter.
