XtConvert(3)                             XT COMPATIBILITY FUNCTIONS                             XtConvert(3)



NAME
       XtConvert, XtDirectConvert - invoke resource converters

SYNTAX
       void XtConvert(Widget w, String from_type, XrmValuePtr from, String to_type, XrmValuePtr to_return);

       void XtDirectConvert(XtConverter converter, XrmValuePtr args, Cardinal num_args, XrmValuePtr from,
              XrmValuePtr to_return);

ARGUMENTS
       args      Specifies the argument list that contains the additional arguments needed to perform the
                 conversion (often NULL).

       converter Specifies the conversion procedure that is to be called.

       from      Specifies the value to be converted.

       from_type Specifies the source type.

       num_args  Specifies the number of additional arguments (often zero).

       to_type   Specifies the destination type.

       to_return Returns the converted value.

       w         Specifies the widget to use for additional arguments (if any are needed).

DESCRIPTION
       The XtConvert function looks up the type converter registered to convert from_type to to_type, com-putes computes
       putes 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  XtConvert has been replaced
       by XtConvertAndStore.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  XtDirectConvert has been replaced by XtCallConverter.
