## Functions
lo_address | lo_address_new (const char *host, const char *port)
| Declare an OSC destination, given IP address and port number.
lo_address | lo_address_new_from_url (const char *url)
| Create a lo_address object from an OSC URL.
void | lo_address_free (lo_address t)
| Free the memory used by the lo_address object.
void | lo_address_set_ttl (lo_address t, int ttl)
| Set the Time-to-Live value for a given target address.
int | lo_address_get_ttl (lo_address t)
| Get the Time-to-Live value for a given target address.
int | lo_send (lo_address targ, const char *path, const char *type,...)
| Send a OSC formatted message to the address specified.
int | lo_send_from (lo_address targ, lo_server from, lo_timetag ts, const char *path, const char *type,...)
| Send a OSC formatted message to the address specified, from the same socket as the specificied server.
int | lo_send_timestamped (lo_address targ, lo_timetag ts, const char *path, const char *type,...)
| Send a OSC formatted message to the address specified, scheduled to be dispatch at some time in the future.
int | lo_address_errno (lo_address a)
| Return the error number from the last failed lo_send or lo_address_new call.
const char * | lo_address_errstr (lo_address a)
| Return the error string from the last failed lo_send or lo_address_new call.
lo_server_thread | lo_server_thread_new (const char *port, lo_err_handler err_h)
| Create a new server thread to handle incoming OSC messages.
lo_server_thread | lo_server_thread_new_multicast (const char *group, const char *port, lo_err_handler err_h)
| Create a new server thread to handle incoming OSC messages, and join a UDP multicast group. Server threads take care of the message reception and dispatch by transparently creating a system thread to handle incoming messages. Use this if you do not want to handle the threading yourself.
lo_server_thread | lo_server_thread_new_with_proto (const char *port, int proto, lo_err_handler err_h)
| Create a new server thread to handle incoming OSC messages, specifying protocol.
void | lo_server_thread_free (lo_server_thread st)
| Free memory taken by a server thread.
lo_method | lo_server_thread_add_method (lo_server_thread st, const char *path, const char *typespec, lo_method_handler h, void *user_data)
| Add an OSC method to the specifed server thread.
void | lo_server_thread_del_method (lo_server_thread st, const char *path, const char *typespec)
| Delete an OSC method from the specifed server thread.
void | lo_server_thread_start (lo_server_thread st)
| Start the server thread.
void | lo_server_thread_stop (lo_server_thread st)
| Stop the server thread.
int | lo_server_thread_get_port (lo_server_thread st)
| Return the port number that the server thread has bound to.
char * | lo_server_thread_get_url (lo_server_thread st)
| Return a URL describing the address of the server thread.
lo_server | lo_server_thread_get_server (lo_server_thread st)
| Return the lo_server for a lo_server_thread.
int | lo_server_thread_events_pending (lo_server_thread st)
| Return true if there are scheduled events (eg. from bundles) waiting to be dispatched by the thread.
lo_blob | lo_blob_new (int32_t size, const void *data)
| Create a new OSC blob type.
void | lo_blob_free (lo_blob b)
| Free the memory taken by a blob.
uint32_t | lo_blob_datasize (lo_blob b)
| Return the ammount of valid data in a lo blob object.
void * | lo_blob_dataptr (lo_blob b)
| Return a pointer to the start of the blob data to allow contents to be changed.
