AIL_file_async_status_callback

The function AIL_file_async_status_callback specifies a user-replaceable callback handler to poll for completion of an asynchronous read.

S32 AILCALLBACK AIL_file_async_status_callback(
  void * async,
  S32 wait,
  U32 *bytes_read
);

In Parameters

async: specifies a pointer to the user structure allocated by the AIL_file_async_read_callback handler.
wait: will be nonzero if the caller expects the function to wait until the asynchronous read is complete.

Out Parameters

bytes_read: specifies an address to which the number of bytes read so far should be stored.

Returns

After updating *bytes_read, this function should return 1 if the asynchronous read operation is complete, or 0 if it is still in progress. If an error condition is detected, 0 should be stored in *bytes_read and 1 should be returned. Asynchronous reads are used on Wii, PS2 and Macintosh by default.
