This API ('LV2') - * attempts to give programmers the ability to write simple 'plugin' - * audio processors in C/C++ and link them dynamically ('plug') into - * a range of these packages ('hosts'). It should be possible for any - * host and any plugin to communicate completely through this interface. - * - * This API is deliberately as short and simple as possible. - * The information required to use a plugin is in a companion data - * (RDF) file. The shared library portion of the API (defined in this - * header) does not contain enough information to make use of the plugin - * possible - the data file is mandatory. - * - * Plugins are expected to distinguish between control rate and audio - * rate data (or other types of data defined by extensions). Plugins have - * 'ports' that are inputs or outputs and each plugin is 'run' for a 'block' - * corresponding to a short time interval measured in samples. Audio rate - * data is communicated using arrays with one element per sample processed, - * allowing a block of audio to be processed by the plugin in a single - * pass. Control rate data is communicated using single values. Control - * rate data has a single value at the start of a call to the 'run()' - * function, and may be considered to remain this value for its duration. - * Thus the 'control rate' is determined by the block size, controlled by - * the host. The plugin may assume that all its input and output ports have - * been connected to the relevant data location (see the 'connect_port()' - * function below) before it is asked to run, unless the port has been set - * 'connection optional' in the plugin's data file. - * - * Plugins will reside in shared object files suitable for dynamic linking - * by dlopen() and family. The file will provide a number of 'plugin - * types' that can be used to instantiate actual plugins (sometimes known - * as 'plugin instances') that can be connected together to perform tasks. - * The host can access these plugin types using the lv2_descriptor() - * function. - * - * This API contains very limited error-handling. - * - * == Threading rules == - * - * Certain hosts may need to call the functions provided by a plugin from - * multiple threads. For this to be safe, the plugin must be written so that - * those functions can be executed simultaneously without problems. - * To facilitate this, the functions provided by a plugin are divided into - * classes: - * - * - Discovery class: lv2_descriptor(), extension_data() - * - Instantiation class: instantiate(), cleanup(), activate(), deactivate() - * - Audio class: run(), connect_port() - * - * Extensions to this specification which add new functions MUST declare in - * which of these classes the functions belong, or define new classes for them. - * The rules that hosts must follow are these: - * - * - When a function from the Discovery class is running, no other - * functions in the same shared object file may run. - * - When a function from the Instantiation class is running for a plugin - * instance, no other functions for that instance may run. - * - When a function is running for a plugin instance, no other - * function in the same class may run for that instance. - * - * Any simultaneous calls that are not explicitly forbidden by these rules - * are allowed. For example, a host may call run() for two different plugin - * instances simultaneously. - */ - - -/* ************************************************************************* */ - - -/** Plugin Handle. - * - * This plugin handle indicates a particular instance of the plugin - * concerned.
