/** @file
* @brief Public core API for Tox clients.
*
* Every function that can fail takes a function-specific error code pointer
* that can be used to diagnose problems with the Tox state or the function
* arguments. The error code pointer can be NULL, which does not influence the
* function's behaviour, but can be done if the reason for failure is irrelevant
* to the client.
*
* The exception to this rule are simple allocation functions whose only failure
* mode is allocation failure. They return NULL in that case, and do not set an
* error code.
*
* Every error code type has an OK value to which functions will set their error
* code value on success. Clients can keep their error code uninitialised before
* passing it to a function. The library guarantees that after returning, the
* value pointed to by the error code pointer has been initialised.
*
* Functions with pointer parameters often have a NULL error code, meaning they
* could not perform any operation, because one of the required parameters was
* NULL. Some functions operate correctly or are defined as effectless on NULL.
*
* Some functions additionally return a value outside their return type domain,
* or a bool containing true on success and false on failure.
*
* All functions that take a Tox instance pointer will cause undefined behaviour
* when passed a NULL Tox pointer.
*
* All integer values are expected in host byte order.
*
* Functions with parameters with enum types cause unspecified behaviour if the
* enumeration value is outside the valid range of the type. If possible, the
* function will try to use a sane default, but there will be no error code,
* and one possible action for the function to take is to have no effect.
*
* Integer constants and the memory layout of publicly exposed structs are not
* part of the ABI.
*
* @section events Events and callbacks
*
* Events are handled by callbacks. One callback can be registered per event.
* All events have a callback function type named `tox_{event}_cb` and a
* function to register it named `tox_callback_{event}`. Passing a NULL
* callback will result in no callback being registered for that event. Only
* one callback per event can be registered, so if a client needs multiple
* event listeners, it needs to implement the dispatch functionality itself.
*
* The last argument to a callback is the user data pointer. It is passed from
* tox_iterate to each callback in sequence. The user data pointer is never
* stored or dereferenced by any library code, so can be any pointer, including
* NULL.
*
* @section threading Threading implications
*
* It is possible to run multiple concurrent threads with a Tox instance for
* each thread. It is also possible to run all Tox instances in the same thread.
* A common way to run Tox (multiple or single instance) is to have one thread
* running a simple tox_iterate loop, sleeping for tox_iteration_interval
* milliseconds on each iteration.
*
* If you want to access a single Tox instance from multiple threads, access
* to the instance must be synchronised. While multiple threads can concurrently
* access multiple different Tox instances, no more than one API function can
* operate on a single instance at any given time.
*
* Functions that write to variable length byte arrays will always have a size
* function associated with them. The result of this size function is only valid
* until another mutating function (one that takes a pointer to non-const Tox)
* is called. Thus, clients must ensure that no other thread calls a mutating
* function between the call to the size function and the call to the retrieval
* function.
*
* E.g. to get the current nickname, one would write
*
* @code
* size_t length = tox_self_get_name_size(tox);
* uint8_t *name = malloc(length);
* if (!name) abort();
* tox_self_get_name(tox, name);
* @endcode
*
* If any other thread calls tox_self_set_name while this thread is allocating
* memory, the length may have become invalid, and the call to
* tox_self_get_name may cause undefined behaviour.
