XtConvert(3)		   XT COMPATIBILITY FUNCTIONS		    XtConvert(3)

NAME
     XtConvert, XtDirectConvert - invoke resource converters

SYNTAX
     #include <X11/Intrinsic.h>

     void  XtConvert(Widget  w,  const	char *from_type, XrmValuePtr from, const
	    char *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 argu-
	       ments 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, 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  XtConvert has been replaced by XtConvertAndStore.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  XtDirectConvert has been replaced by XtCallConverter.
