#include <aio.h> DESCRIPTION
The <aio.h> header defines the aiocb structure which includes the following members: int aio_fildes file descriptor off_t aio_offset file offset volatile void* aio_buf location of buffer size_t aio_nbytes length of transfer int aio_reqprio request priority offset struct sigevent aio_sigevent notification type int aio_lio_opcode listio operation This header also includes the following constants: AIO_ALLDONE A return value indicating that none of the requested operations could be canceled since they are already complete. AIO_CANCELED A return value indicating that all requested operations have been canceled.

LIO_NOP A lio_listio(3C) element operation option indicating that no transfer is requested. LIO_NOWAIT A lio_listio() synchronization operation indicating that the calling thread is to continue execution while the lio_lis- tio() operation is being performed, and notification is to be given when the operation is complete. LIO_READ A lio_listio() element operation option requesting a read. LIO_WAIT A lio_listio() synchronization operation indicating that the calling thread is to suspend until the lio_listio() opera- tion is complete. LIO_WRITE A lio_listio() element operation option requesting a write. SEE ALSO
