# k9core coding style
|
|
|
|
Pretty similar to the GNU code standards.
|
|
|
|
## Functions definition
|
|
|
|
Functions have to begin with return type, breakline, and functionname,
|
|
also brackets will be in a new line:
|
|
|
|
~~~c
|
|
int
|
|
main(int argc, char *argv[])
|
|
~~~
|
|
|
|
## Line length
|
|
|
|
A line of code must no exced 75 characters. If it exceeds, do a
|
|
breakline:
|
|
|
|
~~~c
|
|
|
|
int
|
|
a_very_long_function(int a_very_long_parameter, int
|
|
another_very_long_parameter);
|
|
~~~
|
|
|
|
## Statements
|
|
|
|
Do not do declarations inside an if block. Declarations inside while
|
|
loop are OK.
|
|
|
|
~~~c
|
|
int fd;
|
|
if((fd = open("file", O_CREAT)) == -1) /* Don't do this */
|
|
{
|
|
/* Whatever */
|
|
}
|
|
|
|
/* Do this instead */
|
|
|
|
int fd = open("file", O_CREAT);
|
|
if(fd == -1)
|
|
{
|
|
/* Whatever */
|
|
}
|
|
~~~
|
|
|
|
## Comments
|
|
|
|
Do not use C++ style comments. Comments at beggining of the line
|
|
should explain what the line does. not how it does. Comments at the
|
|
end of the line must be explanations of something:
|
|
|
|
~~~c
|
|
// This is a wrong comment
|
|
|
|
/* This is a correct comment */
|
|
|
|
/* Makes a syscall giving a file descriptor... */
|
|
|
|
fd = open("whatever",O_RDONLY); /* WRONG */
|
|
|
|
/* Creates a file descriptor on the file whatever */
|
|
|
|
fd = open("whatever",O_RDONLY); /* Yes */
|
|
|
|
/* 420 is 644 in decimal */ <- WRONG
|
|
chmod("whatever",420)
|
|
|
|
chmod("whatever",420) /* 420 is 644 in decimal
|
|
