WildMidi_GetOutput - retrieve raw audio data
int WildMidi_GetOutput (midi *handle, char *buffer, unsigned long int
Places size bytes of audio data from a handle, previously opened by
WildMidi_Open(3) or WildMidi_OpenBuffer(3), into a buffer pointer to by
buffer must be atleast size bytes, with size being a multiple of 4 as
the data is stored in 16bit interleaved stereo format.
handle The indentifier obtained from opening a midi file with
WildMidi_Open(3) or WildMidi_OpenBuffer(3)
buffer The location supplied by the calling program where libWildMidi
is to store the audio data.
size The size of the buffer in bytes. Since libWildMidi processes the
audio in 16bit interleaved stereo format, this value needs to be
a multiple of 4.
Returns -1 on error and an error message sent to stderr, 0 when there
is no more audio data, otherwise the number of bytes of audio data
writen to buffer.
NOTE: if the return value is less than the size you gave, this does not
denote an error, it simply means the lib reached the end of the midi
before it could fill the buffer.
