aioread(3)

aioread(3) is the asynchronous version of read(2). In addition to the normal read arguments, aioread takes the arguments specifying a file position and the address of an aio_result_t structure in which the system stores the result information about the operation. The file position specifies a seek to be performed within the file before the operation. Whether the aioread call succeeds or fails, the file pointer is updated.
