2 Constants and Enums

Tox uses several enums and many different constants. It is important to be familiar with the enums, especially.

2.1 Constants

value
TOX_PUBLIC_KEY_SIZE : 32

value
TOX_SECRET_KEY_SIZE : 32

value
TOX_ADDRESS_SIZE
:
(+ TOX_PUBLIC_KEY_SIZE
(ctype-sizeof uint32_t) (ctype-sizeof uint16_t))

value
TOX_MAX_NAME_LENGTH : 128

value
TOX_MAX_STATUS_MESSAGE_LENGTH : 1007

value
TOX_MAX_FRIEND_REQUEST_LENGTH : 1016

2.2 Enums

Tox uses various enumerations in many of its functions and they are explained below.

value
_TOX-USER-STATUS : '(available away busy)

value
_TOX-MESSAGE-TYPE : '(normal action)

value
_TOX-PROXY-TYPE : '(none http socks5)

value
_TOX-ERR-OPTIONS-NEW : '(ok malloc)

value
_TOX-ERR-NEW :
'(ok
  null
  malloc
  port-alloc
  proxy-bad-type
  proxy-bad-host
  proxy-bad-port
  proxy-not-found
  load-encrypted
  load-bad-format)

'malloc is returned when the function was unable to allocate enough memory to store the internal structures for the Tox object.

'port-alloc is returned when the function was unable to bind to a port. This may mean that all ports have already been bound, e.g. by other Tox instances, or it may mean a permission error.

'proxy-bad-type is returned when the proxy-type variable was invalid.

'proxy-bad-host is returned when the proxy-type variable was valid, but the proxy-host had an invalid format or was NULL.

'proxy-bad-port is returned when the proxy-type was valid, but the proxy-port was invalid.

'proxy-not-found is returned when the proxy host passed could not be resolved.

'load-encrypted is returned when the bytes loaded into the function contained an encrypted save.

'load-bad-format is returned when the data format was invalid. This can happen when loading data that was saved by an older version of Tox, or when the data has been corrupted. When loading from badly formatted data, some data may have been loaded, and the rest is discarded.

value
_TOX-ERR-BOOTSTRAP : '(ok null bad-host bad-port)

value
_TOX-CONNECTION : '(none tcp udp)

value
_TOX-ERR-SET-INFO : '(ok null too-long)

value
_TOX-ERR-FRIEND-SEND-MESSAGE :
'(ok
  null
  friend-not-found
  friend-not-connected
  sendq
  too-long
  empty)

'sendq is returned when an allocation error occurred while increasing the send queue size

value
_TOX-FILE-KIND : '(data avatar)

'data is used when sending arbitrary file data. Clients can choose to handle it based on the file name or magic or any other way.

'avatar is used when sending avatar data. Avatars can be sent at any time the client wishes. Generally, a client will send the avatar to a friend when that friend comes online, and to all friends when the avatar changed. A client can save some traffic by remembering which friend received the updated avatar already and only send it if the friend has an out of date avatar. Clients who receive avatar send requests can reject it (by sending TOX_FILE_CONTROL_CANCEL before any other controls), or accept it (by sending TOX_FILE_CONTROL_RESUME). The file_id of length TOX_HASH_LENGTH bytes (same length as TOX_FILE_ID_LENGTH) will contain the hash. A client can compare this hash with a saved hash and send TOX_FILE_CONTROL_CANCEL to terminate the avatar transfer if it matches. When file_size is set to 0 in the transfer request it means that the client has no avatar.

value
_TOX-FILE-CONTROL : '(resume pause cancel)

'resume is used when accepting a file transfer or when resuming a paused transfer.

'pause is sent by clients to pause the file transfer. The initial state of a file transfer is always paused on the receiving side and running on the sending side. If both the sending and receiving side pause the transfer, then both need to send TOX_FILE_CONTROL_RESUME for the transfer to resume.

'cancel is sent by the receiving client to reject a file send request before any other commands are sent. Also sent by either side to terminate a file transfer.

value
_TOX-ERR-FILE-CONTROL :
'(ok
  friend-not-found
  friend-not-connected
  not-found
  not-paused
  denied
  already-paused
  sendq)

'not-found is returned when ; no file transfer with the given file number was found for the given friend.

'denied is returned when a 'resume control was sent, but the file transfer was paused by the other party. Only the party that paused the transfar can resume it.

'senq is returned when the packet queue is full.

value
_TOX-ERR-FILE-SEEK :
'(ok
  friend-not-found
  friend-not-connected
  transfer-not-found
  seek-denied
  invalid-position
  sendq)

'transfer-not-found is returned when no transfer with the given file number was found for the given friend.

'seek-denied is returned when the file was not in a state where it could be seeked.

'invalid-position is returned when the seek position was invalid.

'senq is returned when the packet queue is full.

value
_TOX-ERR-FILE-GET : '(ok friend-not-found transfer-not-found)

'(ok
  null
  friend-not-found
  friend-not-connected

  sendq)

value
_TOX-ERR-KEY-DERIVATION : '(ok null failed)

value
_TOX-ERR-ENCRYPTION :
'(ok
  null
  key-derivation-failed
  encryption-failed)

'null is returned when some input data, or maybe the output pointer, was null.

'key-derivation-failed is returned when the crypto lib was unable to derive a key from the given passphrase, which is usually a lack of memory issue. The functions accepting keys do not produce this error.

'encryption-failed is returned when the encryption itself failed.

value
_TOX-ERR-DECRYPTION :
'(ok
  null
  invalid-length
  bad-format
  key-derivation-failed
  decryption-failed)

value
_TOX-GROUPCHAT-TYPE : '(text av)

3.6 Avatar Handling and Manipulation

procedure
(set-avatar! tox format data [len]) → boolean?
  tox : _Tox-pointer
  format : integer?
  data : bytes?
  len : integer? = (bytes-length data)

Set the user avatar image data.

This should be made before connecting, so we will not announce that the user have no avatar before setting and announcing a new one, forcing the peers to re-download it.

Notice that the library treats the image as raw data and does not interpret it by any way.

Arguments:

format - Avatar image format or NONE for user with no avatar (see TOX_AVATAR_FORMAT);

data - bytes containing the avatar data (may be NULL it the format is NONE);

len - length of image data. Must be <= TOX_AVATAR_MAX_DATA_LENGTH.

returns #t on success

returns #f on failure.

procedure
(unset-avatar! tox) → integer?
tox : _Tox-pointer

Unsets the user avatar.

returns 0 on success (currently always returns 0).

procedure

returns #f on failure.

procedure
(send-avatar-info tox friendnumber) → boolean?
tox : _Tox-pointer
friendnumber : integer?

Send an unrequested avatar information to a friend.

Sends our avatar format and hash to a friend; he/she can use this information to validate an avatar from the cache and may (or not) reply with an avatar data request.

Notice: it is NOT necessary to send this notification after changing the avatar or connecting. The library already does this.

returns #t on success

returns #f on failure.

procedure
(request-avatar-data tox friendnumber) → boolean?
tox : _Tox-pointer
friendnumber : integer?

Request the avatar data from a friend.

procedure
(callback-connection-status tox
anonproc
[ userdata]) → void?
  tox : _Tox-pointer
  anonproc : procedure?

procedure
(callback-avatar-info tox anonproc [userdata]) → void?
  tox : _Tox-pointer
  anonproc : procedure?
  userdata : cpointer? = #f

Set the callback function for avatar information.

This callback will be called when avatar information are received from friends. These events can arrive at anytime, but are usually received upon connection and in reply of avatar information requests.

anonproc is in the form (anonproc tox friendnumber format hash userdata) where ’format’ is the avatar image format (see TOX_AVATAR_FORMAT) and ’hash’ is the hash of the avatar data (in a byte-string) for caching purposes and it is exactly TOX_HASH_LENGTH long. If the image format is NONE, the hash is zeroed.

procedure

This callback will be called when the complete avatar data was correctly received from a friend. This only happens in reply of an avatar data request (see request-avatar-data);

anonproc is in the form (anonproc tox friendnumber img-format img-hash data-ptr datalen userdata) where img-format is the avatar image format (see TOX_AVATAR_FORMAT); img-hash is the locally-calculated cryptographic hash of the avatar data (in a byte-string) and it is exactly TOX_HASH_LENGTH long; data-ptr is the avatar image data (as a pointer) and datalen is the length of such data.

If format is 'NONE, data-ptr is #f, datalen is zero, and the hash is zeroed. The hash is always validated locally with the function tox-hash and ensured to match the image data, so this value can be safely used to compare with cached avatars.

WARNING: users MUST treat all avatar image data received from another peer as untrusted and potentially malicious. The library only ensures that the data which arrived is the same the other user sent, and does not interpret or validate any image data.
