## Member Function Documentation

## ◆ get_interface()

void* openmpt::module_ext::get_interface | ( | const std::string & | interface_id | ) |

Retrieve a libopenmpt extension.

Example: Retrieving the interactive extension to change the tempo of a module:

openmpt::module_ext *mod = new openmpt::module_ext( stream );
#ifdef LIBOPENMPT_EXT_INTERFACE_INTERACTIVE
openmpt::ext::interactive *interactive = static_cast<openmpt::ext::interactive *>( self->mod->get_interface( openmpt::ext::interactive_id ) );
if ( interactive ) {
interactive->set_tempo_factor( 2.0 ); // play module at double speed
} else {
// interface not available
}
#else
// interfae not available
#endif

Parameters

  interface_id | The name of the extension interface to retrieve.

Returns
  The interface object. This may be a nullptr if the extension was not found.
