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 ar-
		 guments 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	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	XtConvert has been replaced by XtCon-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 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.ad-
       dress for non-NULL.  XtDirectConvert has	been replaced by XtCallCon-
       verter.
