NAME io_getevents - Read asynchronous I/O events from the completion queue CONTENTS Author "SYNOPSIS" #include <linux/time.h> #include <linux/aio.h>
#include <linux/time.h>
#include <linux/aio.h>
io_getevents attempts to read at least min_nr events and up to nr events from the completion queue of the AIO context specified by ctx_id. timeout specifies the amount of time to wait for events, where a NULL timeout waits until at least min_nr events have been seen. Note that timeout is relative and will be updated if not NULL and the operation blocks.
"RETURN VALUE" io_getevents returns the number of events read: 0 if no events are available or < min_nr if the timeout has elapsed. "ERRORS"
io_getevents returns the number of events read: 0 if no events are available or < min_nr if the timeout has elapsed.
"ERRORS"
io_getevents is Linux specific and should not be used in programs that are intended to be portable.
"VERSIONS" The asynchronous I/O system calls first appeared in Linux 2.5, August 2002. "SEE ALSO" io_setup(2), io_submit(2), io_getevents(2), io_cancel(2), io_destroy(2). "NOTES" AUTHOR
