|
|
; Description:
|
|
; ---
|
|
; Loads the given XM song and starts playing it as soon as you
|
|
; call uFMOD_WaveOut for the first time. Playback won't begin
|
|
; if XM_SUSPENDED flag is specified. It will stop any currently
|
|
; playing song before loading the new one.
|
|
; ---
|
|
; Parameters:
|
|
; ---
|
|
; lpXM
|
|
; Specifies the song to load. If this parameter is 0, any
|
|
; currently playing song is stopped. In such a case, function
|
|
; does not return a meaningful value. fdwSong parameter
|
|
; determines whether this value is interpreted as a filename
|
|
; or as a pointer to an image of the song in memory.
|
|
; param
|
|
; If XM_MEMORY is specified, this parameter should be the size
|
|
; of the image of the song in memory.
|
|
; If XM_FILE is specified, this parameter is ignored.
|
|
; fdwSong
|
|
; Flags for playing the song. The following values are defined:
|
|
; XM_FILE lpXM points to filename. param is ignored.
|
|
; XM_MEMORY lpXM points to an image of a song in memory.
|
|
; param is the image size. Once, uFMOD_LoadSong
|
|
; returns, it's safe to free/discard the memory
|
|
; buffer.
|
|
; XM_NOLOOP An XM track plays repeatedly by default. Specify
|
|
; this flag to play it only once.
|
|
; XM_SUSPENDED The XM track is loaded in a suspended state,
|
|
; and will not play until the uFMOD_Resume function
|
|
; is called. This is useful for preloading a song
|
|
; or testing an XM track for validity.

|
|
; On success, returns the handle of the Infinity Sound driver.
|

; ---
|
|
; Updates the internal playback buffer.
|
|
; ---
|
|
; Remarks:
|
|
; ---
|
|
; This function should be called from the same thread
|
|
; uFMOD_LoadSong was previously called. Playback doesn't actually
|
|
; begin when calling uFMOD_LoadSong, but when calling uFMOD_WaveOut
|
|
; after a successful uFMOD_LoadSong call. Afterwards, you should
|
|
; call uFMOD_WaveOut repeatedly at least once every 250 ms to
|
|
; prevent "buffer underruns".
|
|
; uFMOD_WaveOut is a non-blocking function. The accuracy of the
|
|
; InfoAPI functions (uFMOD_GetStats, uFMOD_GetRowOrder and
|
|
; uFMOD_GetTime) depends on the periodicity of this function being
|
|
; invoked.

; pat
|

|

; ---
|
|
; Remarks:
|
|
; ---
|
|
; uFMOD doesn't automatically perform Note Off effects before jumping
|
|
; to the target pattern. In other words, the original pattern will
|
|
; remain in the mixer until it fades out. You can use this feature to
|
|
; your advantage. If you don't like it, just insert leading Note Off
|
|
; commands in all patterns intended to be used as uFMOD_Jump2Pattern
|
|
; targets.
|
|
; if the pattern index lays outside of the bounds of the pattern order
|
|
; table, calling this function jumps to pattern 0, effectively
|
|
; rewinding playback.

|

; ---
|
|
; Remarks:
|
|
; ---
|
|
; While paused you can still control the volume (uFMOD_SetVolume) and
|
|
; the pattern order (uFMOD_Jump2Pattern). The RMS volume coefficients
|
|
; (uFMOD_GetStats) will go down to 0 and the progress tracker
|
|
; (uFMOD_GetTime) will "freeze" while the song is paused.
|
|
; uFMOD_Pause doesn't perform the request immediately. Instead, it
|
|
; signals to pause when playback reaches next chunk of data.
|
|
; This way, uFMOD_Pause performs asynchronously and returns very fast.
|
|
; It is not cumulative. So, calling uFMOD_Pause many times in a row
|
|
; has the same effect as calling it once.
|
|
; You shouldn't stop calling uFMOD_WaveOut while the song is paused!

; Remarks:

|
|
; This function is useful for updating a VU meter. It's recommended
|
|
; to rescale the output to log10 (decibels or dB for short), because
|
|
; human ears track volume changes in a dB scale. You may call
|
|
; uFMOD_GetStats() as often as you like, but take in mind that uFMOD
|
|
; updates both channel RMS volumes at the same rate uFMOD_WaveOut
|
|
; function is called. In other words, you should call uFMOD_WaveOut
|
|
; more often to increase the accuracy of uFMOD_GetStats.

|
|
; Remarks:
|
|
; ---
|
|
; This function is useful for synchronization. uFMOD updates both
|
|
; row and order values at the same rate uFMOD_WaveOut function is
|
|
; called. In other words, you should call uFMOD_WaveOut more often
|

; ---
|
|
; Returns the time in milliseconds since the song was started.
|
|
; ---
|
|
; Remarks:
|
|
; ---
|
|
; This function is useful for synchronizing purposes. Multimedia

|
|
; You can use Infinity Sound API to control the L and R channels volumes
|
|
; separately. It also has a wider range than uFMOD_SetVolume, sometimes
