[comp.windows.x] Device Identification under X11

davidh@dent.Berkeley.EDU (David S. Harrison) (02/04/89)

Under X10,  I used to use the DisplayType() macro determine the
device type.  This information was used to allow a user to
customize color and stipple patterns based on a particular
device.  I can't find an equivalent call or macro under X11.
The ServerVendor() macro appears to return information about
the vendor only (no information about the display the server
is driving).  Is there such a call or has this concept been
dropped?

There is no explicit provision for "device type" in X11.  One of the
reasons is that we didn't want to be in the business of acting as
registrar for all the world's devices.  The other is that it's really
the wrong kind of information for most purposes (but I'd have a hard
time giving you any spec for what the right information is :-).  Vendors
can embed device information in the vendor string; whether any do, I
don't know.
