As xsacha also pasted, a lot of this info is in the header file I mentioned: "mm/renderer/events.h". It is probably the easiest to just navigate there, within the QNX Momentics IDE and check out the enum types and functions.
I am pasting some of the others as well:
/**
* The event type.
*/
typedef enum mmr_event_type {
MMR_EVENT_NONE, ///< No pending events.
MMR_EVENT_ERROR, ///< Playback has stopped due to an error or EOF.
MMR_EVENT_STATE, ///< State or speed change, other than an error or EOF.
MMR_EVENT_OVERFLOW, ///< Some state changes lost; the event contains most the recent state.
MMR_EVENT_WARNING, ///< Warning event.
MMR_EVENT_STATUS, ///< Status update (position, buffer level, etc).
MMR_EVENT_METADATA, ///< Metadata update.
MMR_EVENT_PLAYLIST, ///< Playlist window update.
MMR_EVENT_INPUT, ///< An input has been attached or detached, or input parameters changed.
MMR_EVENT_OUTPUT, ///< An output has been attached or detached, or output parameters changed.
MMR_EVENT_CTXTPAR, ///< Context parameters have changed.
MMR_EVENT_TRKPAR, ///< Track parameters have changed.
MMR_EVENT_OTHER, ///< None of the above, but something has changed.
} mmr_event_type_t;
/**
* The context state
*/
typedef enum mmr_state {
MMR_STATE_DESTROYED, ///< The context has been destroyed.
MMR_STATE_IDLE, ///< The context has no input.
MMR_STATE_STOPPED, ///< The context has an input but is not playing.
MMR_STATE_PLAYING, ///< The context is playing or paused.
} mmr_state_t;
/**
* The event structure.
*/
typedef struct mmr_event {
mmr_event_type_t type; ///< The event type
mmr_state_t state; ///< The context state -- valid even when type==MMR_EVENT_NONE
int speed; ///< The playback speed (0 means paused)
union mmr_event_details {
struct mmr_event_state {
mmr_state_t oldstate; ///< The state before the event
int oldspeed; ///< The speed before the event
} state; ///< When type is STATE
struct mmr_event_error {
mmr_error_info_t info; ///< The error info
} error; ///< When type is ERROR
struct mmr_event_warning {
const char *str; ///< The warning string, as a C string
const strm_string_t *obj; ///< The warning string, as a strm_string_t (shareable dictionary string)
} warning; ///< When type is WARNING
struct mmr_event_metadata {
unsigned index; ///< The playlist index for playlist-related events; otherwise, zero
} metadata; ///< When type is METADATA
struct mmr_event_trkparam {
unsigned index; ///< The playlist index
} trkparam; ///< When type is TRKPAR
struct mmr_event_playlist {
unsigned start; ///< The index of the first item in the window
unsigned end; ///< The index of the last item in the window
unsigned length; ///< The playlist length
} playlist; ///< When type is PLAYLIST
struct mmr_event_output {
unsigned id; ///< Output ID
} output; ///< When type is OUTPUT
} details;
const strm_string_t *pos_obj; ///< The position for STATUS, ERROR, and WARNING events; otherwise NULL
const char *pos_str; ///< The position for STATUS, ERROR, and WARNING events; otherwise NULL
const strm_dict_t *data; ///< The full content of the affected object (NULL if object deleted)
const char *objname; ///< The name of the affected object
void *usrdata; ///< The user data associated with this object, or NULL if new object
} mmr_event_t;
