Hello all,
I'm having an infuriating issue with number comparison. Basically I've written a script that runs in cygwin that SSH's to 4 servers, figures out a success percentage and if it is less than a certain point, triggers an alarm. I've managed to get it to connect to the servers, figure out... (5 Replies)

INTRO(9) BSD Kernel Developer's Manual INTRO(9)NAME
intro -- introduction to system kernel interfaces
DESCRIPTION
This section contains information about the interfaces and subroutines in the kernel.
PROTOTYPES ANSI-C AND ALL THAT
Yes please.
We would like all code to be fully prototyped.
If your code compiles cleanly with cc -Wall we would feel happy about it. It is important to understand that this is not a question of just
shutting up cc, it is a question about avoiding the things it complains about. To put it bluntly, do not hide the problem by casting and
other obfuscating practices, solve the problem.
INDENTATION AND STYLE
Believe it or not, there actually exists a guide for indentation and style. It is not generally applied though.
We would appreciate if people would pay attention to it, and at least not violate it blatantly.
We do not mind it too badly if you have your own style, but please make sure we can read it too.
Please take time to read style(9) for more information.
NAMING THINGS
Some general rules exist:
1. If a function is meant as a debugging aid in DDB, it should be enclosed in
#ifdef DDB
#endif /* DDB */
And the name of the procedure should start with the prefix DDB_ to clearly identify the procedure as a debugger routine.
SCOPE OF SYMBOLS
It is important to carefully consider the scope of symbols in the kernel. The default is to make everything static, unless some reason
requires the opposite.
There are several reasons for this policy, the main one is that the kernel is one monolithic name-space, and pollution is not a good idea
here either.
For device drivers and other modules that do not add new internal interfaces to the kernel, the entire source should be in one file if possi-
ble. That way all symbols can be made static.
If for some reason a module is split over multiple source files, then try to split the module along some major fault-line and consider using
the number of global symbols as your guide. The fewer the better.
