NAME

       WildMidi_GetOutput - retrieve raw audio data

LIBRARY

       libWildMidi

SYNOPSIS

       #include <wildmidi_lib.h>

       int WildMidi_GetOutput (midi *handle, int8_t *buffer, uint32_t size);

DESCRIPTION

       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.

       buffer must be at least size bytes, with size being a multiple of 4 as the data is  stored
       in 16bit interleaved stereo format.

       handle The  identifier  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.  The  audio  data will be stored as signed 16bit interleaved stereo in
              native-endian byte order.

       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.

RETURN VALUE

       Returns  -1  on  error along with an error message sent to stderr, 0 when there is no more
       audio data, otherwise the number of bytes of audio data written 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.
