59 The <\fBaio.h\fR> header defines the \fBaiocb\fR structure which includes the
64 int aio_fildes file descriptor
65 off_t aio_offset file offset
66 volatile void* aio_buf location of buffer
67 size_t aio_nbytes length of transfer
68 int aio_reqprio request priority offset

70 int aio_lio_opcode listio operation
76 This header also includes the following constants:
80 \fB\fBAIO_ALLDONE\fR\fR
83 A return value indicating that none of the requested operations could be
84 canceled since they are already complete.
90 \fB\fBAIO_CANCELED\fR\fR
93 A return value indicating that all requested operations have been canceled.
99 \fB\fBAIO_NOTCANCELED\fR\fR
102 A return value indicating that some of the requested operations could not be
103 canceled since they are in progress.
112 A \fBlio_listio\fR(3C) element operation option indicating that no transfer is
119 \fB\fBLIO_NOWAIT\fR\fR
122 A \fBlio_listio()\fR synchronization operation indicating that the calling
123 thread is to continue execution while the \fBlio_listio()\fR operation is being
124 performed, and notification is to be given when the operation is complete.
133 A \fBlio_listio()\fR element operation option requesting a read.
142 A \fBlio_listio()\fR synchronization operation indicating that the calling
143 thread is to suspend until the \fBlio_listio()\fR operation is complete.
149 \fB\fBLIO_WRITE\fR\fR
152 A \fBlio_listio()\fR element operation option requesting a write.
