Coding Style¶
Please refer to Linux kernel coding style for the coding style of C language. There may be some differences in specific Linux kernel versions, such as Linux 4.19, but overall it won't change much.
You could use indent modify your source code:
# Output to stdout
$ indent --linux-style -st main.c
# Or override main.c
$ indent --linux-style main.c
VIM Config¶
The basic configuration of the .vimrc file is as follows:
set tabstop=8
set softtabstop=8
set shiftwidth=8
set cc=80
Code File Format¶
ULPatch use Unix format not DOS or Mac format.
As you can see from manual of dos2unix(1)
In DOS/Windows text files a line break, also known as newline, is a combination of two characters: a Carriage Return (CR) followed by a Line Feed (LF). In Unix text files a line break is a single character: the Line Feed (LF). In Mac text files, prior to Mac OS X, a line break was single Carriage Return (CR) character. Nowadays Mac OS uses Unix style (LF) line breaks.
You may often see the special character ^M under Unix like system if code is DOS or Mac format.
Programming Standards¶
- Never use
%s+strerror(errno)display string describing error number in log, use%minstead.
