# 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
~~~
