- NAME
- CreatePlayerA -- create a player and link it to a conductor. (V37)
- CreatePlayer -- varargs stub for CreatePlayerA(). (V37)
-
- SYNOPSIS
- player = CreatePlayerA(tagList);
- D0 A0
-
- struct Player *CreatePlayerA(struct TagItem *);
-
- player = CreatePlayer(firstTag, ...);
-
- struct Player *CreatePlayer(Tag, ...);
-
- FUNCTION
- Creates a player structure with the desired attributes.
-
- INPUTS
- tagList - pointer to an array of tags providing optional extra
- parameters, or NULL
-
- TAGS
- PLAYER_Name (STRPTR) - name of the player (generally the
- application's name). Default is no name. (V37)
-
- PLAYER_Hook (struct Hook *) - function to call when time changes
- occur. Default is no function. The Hook is called
- with:
-
- A0 - address of Hook structure
- A1 - message, currently pmTime or pmState
- A2 - address of Player structure
-
- Note that your hook function is not necessarily called
- TICK_FREQ times per second. This is the maximum number
- of times it can be called. (V37)
-
- PLAYER_Priority (BYTE) - priority for the player, from -128 to +127.
- Default is 0. (V37)
-
- PLAYER_Conductor (STRPTR) - name of the conductor to link with. If
- this conductor doesn't exist, it is created
- automatically. If ~0 is passed, creates a private
- conductor. (V37)
-
- PLAYER_Ready (BOOL) - set/clear the "ready" flag. Default is FALSE.
- (V37)
-
- PLAYER_AlarmTime (LONG) - sets this player's alarm time, and the
- PLAYERF_ALARMSET flag. (V37)
-
- PLAYER_Alarm (BOOL) - if TRUE sets the PLAYERF_ALARMSET flag, FALSE
- clears the flag. Default is FALSE. (V37)
-
- PLAYER_AlarmSigTask (struct Task *) - task to signal on notify or
- alarm. Default is no task. Having no task automatically
- forces the PLAYERF_ALARMSET flag off. (V37)
-
- PLAYER_AlarmSigBit (BYTE) - signal bit to use on alarm or -1 to
- disable. Default is -1. Having a signal bit of -1
- automatically forces the PLAYERF_ALARMSET flag
- off. (V37)
-
- PLAYER_Quiet (BOOL) - when TRUE, this player is ignored. Mainly
- used by external sync applications. Default is FALSE.
- (V37)
-
- PLAYER_UserData (VOID *) - sets the player's UserData value.
- Default is NULL. (V37)
-
- PLAYER_ID (UWORD) - sets the player's ID value. Default is 0. (V37)
-
- PLAYER_Conducted (BOOL) - if TRUE sets the PLAYERF_CONDUCTED flag,
- FALSE clears the flag. Default is FALSE. (V37)
-
- PLAYER_ExtSync (BOOL) - if TRUE, attempts to become external sync
- source. (V37)
-
- PLAYER_ErrorCode (LONG *) - optional pointer to a longword which
- will receive an error code whenever this function
- fails. Possible error values currently include:
- RTE_NOMEMORY - memory allocation failed
- RTE_NOTIMER - timer (CIA) allocation failed
-
- RESULTS
- player - a pointer to a Player structure on success or NULL on
- failure. When NULL is returned, an error code can be returned
- in the longword variable pointed to by the optional
- PLAYER_ErrorCode tag.

- D0 A0 D0 D1
-
- BOOL ExternalSync(struct Player *, LONG, LONG);
-
- FUNCTION

- until they are free.
-
- INPUTS
- lockType - the internal list to lock. Only RT_CONDUCTORS is
- currently defined.

-
- struct Conductor *NextConductor(struct Conductor *);
-
- FUNCTION
- Returns the next conductor on realtime.library's conductor list. If
- previousConductor is NULL, returns the first conductor in the list.
- Returns NULL if no more conductors.
-
- The conductor list must be locked before calling this function. This
- is done by calling LockRealTime(RT_CONDUCTORS).

-
- FUNCTION
- Changes the play state of the conductor referenced by the
- player. The states can be CONDSTATE_STOPPED, CONDSTATE_PAUSED,
- CONDSTATE_LOCATE, CONDSTATE_RUNNING, or the special value
- CONDSTATE_METRIC which asks the highest priority conducted node
- to do a CONDSTATE_LOCATE, or the special value CONDSTATE_SHUTTLE
- which informs the players that the clock value is changing, but the
- clock isn't actually running. Note that going from CONDSTATE_PAUSED
- to CONDSTATE_RUNNING does not reset the cdt_ClockTime of the
- conductor.
-
- INPUTS
- player - player referencing the conductor to change
- state - new play state of conductor
- time - start time offset in realtime.library heartbeat units
