Is it possible from a running program to determine what the minor version numbers is for X11? It sure would be nice if xrdb would define a symbol like X11R2 or X11R3 based on which version was actually in use. --Dan Ehrlich Dan Ehrlich <ehrlich@shire.cs.psu.edu> | Disclaimer: The opinions expressed are The Pennsylvania State University | my own, and should not be attributed Department of Computer Science | to anyone else, living or dead.

Is it possible from a running program to determine what the minor version numbers is for X11? Yes and no. First, I think you really mean "release number", not "minor version number". "Minor version number" would indicate a change to the underlying X protocol, and from Xlib is found with ProtocolRevision(). The "release number" of a server can be obtained with VendorRelease(), but the interpretation of this number is up to each vendor, there's no guarantee it matches the MIT release number. So, you need to check ServerVendor() as well. For an MIT distribution, this string will be "MIT X Consortium". And, of course, there's no guarantee that all clients on a given machine will all correspond to that vendor's release. It sure would be nice if xrdb would define a symbol like X11R2 or X11R3 based on which version was actually in use. It sounds pretty hard to decide what you really mean here.

From my .X11init:
if [ $HOSTTYPE = hp300 ]
then
X11VERSION=X11R2
else
X11VERSION=X11R3
fi
xrdb -D$X11VERSION -load $HOME/.X11defaults
From my .X11toolstart:
#ifdef X11R2
*Font: courr12
#else
*Font: *-courier-medium-r-*-*-*-120-*-*-*-*-*-*
#endif
This depends upon our knowing that HP hasn't shipped R3 yet, or at
least that we don't have it installed yet. When we get R3 on our
hp300s all this will have to change. Is there an easier way?

We are running a mix of both X11R2 (mostly on RTs) and X11R3 (mostly on Suns). I would like to be able to put something like: #ifdef X11R3 #define big_font courr18 #define normal_font courr14 #define bold_font courb14 #else X11R3 #define big_font 9x15 #define normal_font 8x13 #define bold_font 8x13bold #endif X11R3 at the beginning of the .X{default,resources} files so as to not need the old fonts when we switch completely over the X11R3. At the moment this is done in the script we start X with by looking at the type of machine we are running on. I.E. if a Sun then X11R3 else X11R2. This information is then communicated to xrdb with -DX11R? when the file is loaded into the resource manager. I was just looking for a cleaner way of doing this. --Dan
