Typedef Documentation

  typedef void* lo_address

A reference to an OSC service.

Created by calls to lo_address_new() or lo_address_new_from_url().

  typedef void* lo_blob

A object to store an opaque binary data object.

Can be passed over OSC using the 'b' type. Created by calls to lo_blob_new().

  typedef void* lo_bundle

A low-level object used to represent bundles of messages passed over OSC.

Created by calls to lo_bundle_new(), messages can be added with calls to lo_bundle_add_message().

  typedef void(* lo_err_handler)(int num, const char *msg, const char *where)

A callback function to receive notifcation of an error in a server or server thread.

On callback the paramters will be set to the following values:

Parameters:
    num An error number that can be used to identify this condition.
    msg An error message describing the condidtion.
    where A string describing the place the error occured - typically either a function call or method path.

  typedef void* lo_message

A low-level object used to represent messages passed over OSC.

Created by calls to lo_message_new(), arguments can be added with calls to lo_message_add_*().

  typedef void* lo_method

An object representing an method on a server.

Returned by calls to lo_server_thread_add_method() and lo_server_add_method().

  typedef int(* lo_method_handler)(const char *path, const char *types, lo_arg **argv, int argc, lo_message msg, void *user_data)

A callback function to receive notifcation of matching message arriving in the server or server thread.

On callback the paramters will be set to the following values:

Parameters:
    path That path that the incoming message was sent to
    types If you specided types in your method creation call then this will match those and the incoming types will have been coerced to match, otherwise it will be the types of the arguments of the incoming message.
    argv An array of lo_arg types containing the values, e.g. if the first argument of the incoming message is of type 'f' then the vlaue will be found in argv[0]->f.
    argc The number of argumets received.
    msg A structure containing the original raw message as received. No type coercion will have occured and the data will be in OSC byte order (bigendian).
    user_data This contains the user_data value passed in the call to lo_server_thread_add_method.

  typedef void* lo_server

An object representing an instance of an OSC server.

Created by calls to lo_server_new(). If you with the library to take care of the threading as well you can just use server threads instead.

  typedef void* lo_server_thread

An object representing a thread containing an OSC server.

Created by calls to lo_server_thread_new().
