NAME
io_cancel - cancel an outstanding asynchronous I/O operationSYNOPSIS
#include <libaio.h> int io_cancel(aio_context_t ctx_id, struct iocb *iocb, struct io_event *result); Link with -laio.
DESCRIPTION
io_cancel() attempts to cancel an asynchronous I/O operation previously submitted with io_submit(2). ctx_id is the AIO context ID of the operation to be canceled. If the AIO context is found, the event will be canceled and then copied into the memory pointed to by result without being placed into the completion queue.
RETURN VALUE
io_cancel() returns 0 on success; on failure, it returns one of the errors listed under ERRORS.
ERRORS
- EINVAL
- The AIO context specified by ctx_id is invalid.
- EFAULT
- One of the data structures points to invalid data.
- EAGAIN
- The iocb specified was not canceled.
- ENOSYS
- io_cancel() is not implemented on this architecture.
VERSIONS
The asynchronous I/O system calls first appeared in Linux 2.5, August 2002.
CONFORMING TO
io_cancel() is Linux-specific and should not be used in programs that are intended to be portable.
