aiowrite(3AIO)

aiowrite(3AIO) is the asynchronous version of write(2). In addition to the normal write arguments, aiowrite(3AIO) takes arguments specifying a file position and the address of an aio_result_t structure in which the system is to store the resulting information about the operation.

The file position specifies a seek to be performed within the file before the operation. If the aiowrite(3AIO) call succeeds, the file pointer is updated to the position that would have resulted in a successful seek and write. The file pointer is also updated when a write fails to allow for subsequent write requests.
