From 2b8dd0d6ee4309d74efb7d4f28086e91381fd72a Mon Sep 17 00:00:00 2001 From: "Jason A. Donenfeld" Date: Wed, 27 Jul 2016 11:30:05 +0200 Subject: c: specify static array size in function params The C standard states: A declaration of a parameter as ``array of type'' shall be adjusted to ``qualified pointer to type'', where the type qualifiers (if any) are those specified within the [ and ] of the array type derivation. If the keyword static also appears within the [ and ] of the array type derivation, then for each call to the function, the value of the corresponding actual argument shall provide access to the first element of an array with at least as many elements as specified by the size expression. By changing void func(int array[4]) to void func(int array[static 4]), we automatically get the compiler checking argument sizes for us, which is quite nice. --- src/hashtables.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/hashtables.h') diff --git a/src/hashtables.h b/src/hashtables.h index ed9506b..d51c0d8 100644 --- a/src/hashtables.h +++ b/src/hashtables.h @@ -16,7 +16,7 @@ struct pubkey_hashtable { void pubkey_hashtable_init(struct pubkey_hashtable *table); void pubkey_hashtable_add(struct pubkey_hashtable *table, struct wireguard_peer *peer); void pubkey_hashtable_remove(struct pubkey_hashtable *table, struct wireguard_peer *peer); -struct wireguard_peer *pubkey_hashtable_lookup(struct pubkey_hashtable *table, const uint8_t pubkey[NOISE_PUBLIC_KEY_LEN]); +struct wireguard_peer *pubkey_hashtable_lookup(struct pubkey_hashtable *table, const uint8_t pubkey[static NOISE_PUBLIC_KEY_LEN]); struct index_hashtable { DECLARE_HASHTABLE(hashtable, 10); -- cgit v1.2.3-59-g8ed1b
