====== Things to consider ======

==== Naming ====
<code c>
int variable, descriptive_variable_name;

typedef int own_datatypes_t;

void function_names(void);

void mylib_library_function_with_prefix(void);

typedef enum myenum_t
{
  MYLIB_GLOBAL_SCOPE_ENUM,
} myenum_t;

const int constant;

#define ANY_DEFINE_OR_MACRO

</code>


==== Embracing ====

<code c>

void foo(void)
{
}

if(a)
{
}

switch(a)
{
  case A:
    break;
  case B:
  case C:
    break;
  default:
    break;
}
</code>


==== Conditional statement whitespaces ====

<code c>
if(a == b)

// Not any of these
if (a == b)
if( a == b )

// Compare to function call
strlen (str)
strlen( str )
</code>

==== Whitespaces in declarations ====

<code c>
uint32_t *my_func();
uint32_t* my_func();
uint32_t * my_func();

uint32_t *my_var;
uint32_t* my_var;
uint32_t * my_var;
uint32_t *my_var, *another_var, third_var;

void a_function_with_a_really_long_name_and_argument_list(int that, int makes, int you, int wonder, int where
                                                          int and_how, int to, int break_the, int lines);
</code>

==== Program flow ====

  * Should functions only have one return statement? How/when/why?
