Member Function Documentation

static void RtMidi::getCompiledApi ( std::vector< RtMidi::Api > &  apis) throw ()
static

A static function to determine the available compiled MIDI APIs.

The values returned in the std::vector can be compared against the enumerated list values. Note that there can be more than one API compiled for certain operating systems.

static std::string RtMidi::getApiName ( RtMidi::Api  api)
static

Return the name of a specified compiled MIDI API.

This obtains a short lower-case name used for identification purposes. This value is guaranteed to remain identical across library versions. If the API is unknown, this function will return the empty string.

static std::string RtMidi::getApiDisplayName ( RtMidi::Api  api)
static

Return the display name of a specified compiled MIDI API.

This obtains a long name used for display purposes. If the API is unknown, this function will return the empty string.

static RtMidi::Api RtMidi::getCompiledApiByName ( const std::string &  name)
static

Return the compiled MIDI API having the given name.

A case insensitive comparison will check the specified name against the list of compiled APIs, and return the one which matches. On failure, the function returns UNSPECIFIED.

virtual bool RtMidi::isPortOpen ( void  ) const
pure virtual

Returns true if a port is open and false if not.

Note that this only applies to connections made with the openPort() function, not to virtual ports.

Implemented in RtMidiOut, and RtMidiIn.

virtual void RtMidi::setErrorCallback ( RtMidiErrorCallback  errorCallback = NULL,
void *  userData = 0 
)
pure virtual

Set an error callback function to be invoked when an error has occured.

The callback function will be called whenever an error has occured. It is best to set the error callback function before opening a port.

Implemented in RtMidiOut, and RtMidiIn.
