### AUDIO_LOAD (44h) - Remarks

The pbBuffer field of the MCI_AUDIO_LOAD structure must point to the start of the buffer where the code is loaded. The ulSize field must be set to the number of bytes of loaded code (which is the size of the file). The ulFlags field permits loading the file in multiple pieces. To do this, the first piece is written with the LOAD_START flag set and the last piece with the LOAD_END flag set. All intermediate pieces have both flags cleared. To load the file in a single piece, both flags are set. Notice that the first buffer written must be at least 128 bytes in length.
