Omit parameter names from function prototypes when the names do not
give useful information, e.g.:
- int netdev_get_mtu(const struct netdev *);
+ int netdev_get_mtu(const struct netdev *, int *mtup);

Exception 2: Put a space between the () used in a cast and the
expression whose type is cast: (void *) 0.
- Break long lines before binary operators and the ternary operators ?
-and :, rather than after them, e.g.

- if (first_long_condition() || second_long_condition()

precedence makes it necessary, or unless the operands are themselves
expressions that use && and ||. Thus:
- if (!isdigit(s[0]) || !isdigit(s[1]) || !isdigit(s[2])) {
+ if (!isdigit((unsigned char)s[0])
+ || !isdigit((unsigned char)s[1])
+ || !isdigit((unsigned char)s[2])) {
printf("string %s does not start with 3-digit code\n", s);
