XtConvert(3Xt)		  XT COMPATIBILITY FUNCTIONS	       XtConvert(3Xt)



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
       the conversion (often NULL)

       args	 Specifies the argument list that contains the additional
		 arguments needed to perform.

       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 con-
       vert from_type to to_type, computes any additional arguments needed,
       and then calls XtDirectConvert.	XtConvert has been replaced by XtCon-
       vertAndStore.

       The XtDirectConvert function looks in the converter cache to see if
       this conversion procedure has been called with the specified argu-
       ments.  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	XtDirectConvert has been replaced by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.
