From 8e0eeff79f8cf355221b457bf458765ba1f59537 Mon Sep 17 00:00:00 2001 From: iphydf Date: Sun, 28 Aug 2016 20:00:05 +0100 Subject: Expose constants as functions. These functions simply return the constants. They are a stable ABI, so that if constants change, the ABI of these functions won't. Code solely relying on these functions will remain compatible with future values of those constants. The functions are currently not exposed in tox.h, because this is pending a change in apidsl to generate accessors for "const" values. --- toxcore/tox.c | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) (limited to 'toxcore/tox.c') diff --git a/toxcore/tox.c b/toxcore/tox.c index 4b96afa8..1063f806 100644 --- a/toxcore/tox.c +++ b/toxcore/tox.c @@ -95,6 +95,25 @@ bool tox_version_is_compatible(uint32_t major, uint32_t minor, uint32_t patch) } +#define CONST_FUNCTION(lowercase, uppercase) \ +uint32_t tox_##lowercase(void) \ +{ \ + return TOX_##uppercase; \ +} + +CONST_FUNCTION(public_key_size, PUBLIC_KEY_SIZE) +CONST_FUNCTION(secret_key_size, SECRET_KEY_SIZE) +CONST_FUNCTION(address_size, ADDRESS_SIZE) +CONST_FUNCTION(max_name_length, MAX_NAME_LENGTH) +CONST_FUNCTION(max_status_message_length, MAX_STATUS_MESSAGE_LENGTH) +CONST_FUNCTION(max_friend_request_length, MAX_FRIEND_REQUEST_LENGTH) +CONST_FUNCTION(max_message_length, MAX_MESSAGE_LENGTH) +CONST_FUNCTION(max_custom_packet_size, MAX_CUSTOM_PACKET_SIZE) +CONST_FUNCTION(hash_length, HASH_LENGTH) +CONST_FUNCTION(file_id_length, FILE_ID_LENGTH) +CONST_FUNCTION(max_filename_length, MAX_FILENAME_LENGTH) + + void tox_options_default(struct Tox_Options *options) { if (options) { -- cgit v1.2.3
