Wwise SDK 2018.1.11

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.

备注

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().

返回

• AK_Success: transfer was successful and out_pBuffer is filled with data.
• AK_Fail: an error occured.

参数

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.
