MF_API int MFSound_Lock ( MFSound *  pSound, size_t  offset, size_t  bytes, void **  ppData, size_t *  pSize, void **  ppData2 = NULL, size_t *  pSize2 = NULL  ) Locks a sound buffer for writing. Parameters pSound Pointer to the sound to lock. offset Offset into the sound buffer, in bytes. bytes Number of bytes to lock. If bytes is 0, the entire buffer is locked. ppData Pointer to a pointer that receives the address of the locked buffer portion. pSize Pointer to an int the receives the size of the locked buffer portion. ppData2 Pointer to a pointer that receives the second locked portion, or NULL. This is only used when locking a circular buffer and the lock length exceeds the buffers length. This parameter may be NULL. pSize2 Pointer to an int the receives the size of the locked buffer portion. This parameter may be NULL. Returns Returns 0 on success.
