Re: [trinity-devel] %s, %h variables, etc.

Okay. Let me back up. I think this is two questions. Calvin, yes, this is a stdlib variable. First, in KDM kdmrc is a list of variables: %d -> current display %h -> host name, possibly with domain name %n -> node name, most probably the host name without domain name %s -> the operating system %r -> the operating system's version %m -> the machine (hardware) type I was partially trying to remember that list. That list should not be confused with the specific usage I want to understand, which is found in tdebase/kdm/backend/error.c:102: sprintf( buf, "/var/log/%s.log", prog ); When I look in /var/log, I know that "%s" is translated to "kdm." As I am learning C/C++, I know that %s in that line is stdlib for string, and "prog" is the data to be passed to sprintf as a string. What is the value of "prog"? I see that dm.h is part of the preprocessor includes. In dm.h, prog is defined as an extern char variable. (Although I don't know what the asterisk means. :) ) I still don't where prog is assigned the value of "kdm." I want to submit a patch for bug report 618, which I created. A simple bug report like this is a good way to help me learn a little more about C++. When I better understand the context of %s in error.c, that is, where prog is assigned the value of kdm, I can submit a patch. Darrell
