Naming conventions
------------------

- We don't use capital letters, except on defines and enumerators 
  (see below).

- Public APIs are always prefixed by the name of that module:
  ltfs.c: ltfs_statfs(), ltfs_open(), ltfs_close(), ltfs_read()
  fs.c: fs_resolve_dentry(), fs_set_name(), fs_set_creation_time()


Spaces, tabs and commas
-----------------------

When indenting the code, always use TABs with 4 spaces. Do not
replace TABs by spaces.

When writing arguments to a function or defining enums, also use 
the following comma conventions:

call_function(arg1, arg2, arg3);

call_another_function(
	very_long_argument1,
	very_long_argument2,
	very_long_argument3
	);

enum very_cool_enumerator {
	VERY_COOL_1,
	VERY_COOL_2,
	VERY_COOL_3,
};


Macros and defines
------------------

When defining wrappers around functions using macros do that
using lowercase characters. Defines always go in uppercase.

#define wrapper_around_some_function(x,y) \
	...

#define LTFS_MAX_VALUE 2112


Functions
---------

Return type, function name and its parameters should go all
in a single line, except if the parameters are too long.

void ltfs_function(void *params)
{
}

void ltfs_function_with_many_parameters(void *params1,
	void *params2, void *params3)
{
}


Conditional tests
-----------------

if (condition) {
	line 1;
	line 2;
} else
	line 3;

if (another condition)
	do this;
else
	do that;

if (yet another condition) {
	/* 
	 * It's ok to open brackets when adding comments,
	 * just to make it clear where the scope ends.
	 * That can improve readability when comments
	 * span across multiple lines.
	 */
	 do something else;
}


Loops
-----

for (x=start; x<end; ++x) {
	body
}


Comments
--------

Please do not use C++ style comments (//), except when
temporarily commenting out a line of code. If too many
lines are being commented out consider using #if 0 instead
or, preferably, just remove that code completely.

For comments, always use the C style (/* comments */), 
even if that's just a single line.

For documenting functions, please use the Doxygen-friendly
format below:

/**
 * General comments about the function go here.
 * @param var1 Describe what var1 does.
 * @param var2 Describe what var2 does.
 * @return Describe what's expected to be returned both on
 *  success and on error situation. Also, note that we
 *  tabulate with one extra space when the comments span
 *  multiple lines.
 */
int function(void *var1, void *var2)
{
}


Maximum line length
-------------------

Lines must not exceed 100 characters.
