NAME

io_getevents - Read resulting events from io requests  

SYNOPSIS

#include <errno.h>


#include <libaio.h>
struct iocb { void *data; unsigned key; short aio_lio_opcode; short aio_reqprio; int aio_fildes; }; struct io_event { unsigned PADDED(data, __pad1); unsigned PADDED(obj, __pad2); unsigned PADDED(res, __pad3); unsigned PADDED(res2, __pad4); }; int io_getevents(io_context_t ctx, long nr, struct io_event *events[], struct timespec *timeout);
 

DESCRIPTION

Attempts to read up to nr events from the completion queue for the aio_context specified by ctx.  

RETURN VALUES

May return 0 if no events are available and the timeout specified by when has elapsed, where when == NULL specifies an infinite timeout. Note that the timeout pointed to by when is relative and will be updated if not NULL and the operation blocks. Will fail with ENOSYS if not implemented.  

ERRORS

EINVAL
if ctx_id is invalid, if min_nr is out of range, if nr is out of range, if when is out of range.
EFAULT
if any of the memory specified to is invalid.
