aio_suspend

Suspends the calling process until one of the asynchronous I/O operations completes.

Syntax

int aio_suspend(const struct aiocb * const cblist[], int n, const struct timespec *timeout);
Arguments
cblist[]
Pointer to a control block on which I/O is initiated
n
Length of
cblist
list
*timeout
Time interval to suspend the calling process
Description
The
aio_suspend()
function is like a wait operation. It suspends the calling process until,
  • At least one of the asynchronous I/O requests in the list
    cblist
    of length
    n
    has completed
  • A signal is delivered
  • The time interval indicated in
    timeout
    is not
    NULL
    and has passed.
Each item in the
cblist
list must either be
NULL
(when it is ignored), or a pointer to a control block on which I/O was initiated using
aio_read()
,
aio_write()
, or
lio_listio()
functions.
Returns
0
: On success
-1
: On error
To get the correct error code, use
errno
.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
