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 argu-
ments (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XtConvert has been replaced by XtConvertAndStore.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XtDirectConvert has been replaced by XtCallConverter.
