◆ Read()

virtual AKRESULT AK::StreamMgr::IAkIOHookBlocking::Read ( AkFileDesc in_fileDesc,
const AkIoHeuristics in_heuristics,
void *  out_pBuffer,
AkIOTransferInfo in_transferInfo 
)
pure virtual

Reads data from a file (synchronous). Read data from the file described by in_fileDesc, in address out_pBuffer and with size and position passed within io_transferInfo. When transfer is complete, return with the proper return code.

Remarks
File position passed in io_transferInfo takes the offset of this file relative to AkFileDesc::hFile (described with AkFileDesc::uSector). It is computed by the high-level device as "in_fileDesc.uSector * Block_Size + Stream_Position", where Block_Size is obtained via AK::StreamMgr::IAkLowLevelIOHook::GetBlockSize().
Returns
  • AK_Success: transfer was successful and out_pBuffer is filled with data.
  • AK_Fail: an error occured.
Parameters
in_fileDesc File descriptor.
in_heuristics Heuristics for this data transfer.
out_pBuffer Buffer to be filled with data.
in_transferInfo Synchronous data transfer info.
