aiocancel(3AIO) Asynchronous I/O Library Functions aiocancel(3AIO)NAMEaiocancel - cancel an asynchronous operation
SYNOPSIS
cc [ flag ... ] file ... -laio [ library ... ]
#include <sys/asynch.h>
int aiocancel(aio_result_t *resultp);
DESCRIPTIONaiocancel() cancels the asynchronous operation associated with the
result buffer pointed to by resultp. It may not be possible to immedi‐
ately cancel an operation which is in progress and in this case, aio‐
cancel() will not wait to cancel it.
Upon successful completion, aiocancel() returns 0 and the requested
operation is cancelled. The application will not receive the SIGIO
completion signal for an asynchronous operation that is successfully
cancelled.
RETURN VALUES
Upon successful completion, aiocancel() returns 0. Upon failure, aio‐
cancel() returns −1 and sets errno to indicate the error.
ERRORSaiocancel() will fail if any of the following are true:
EACCES The parameter resultp does not correspond to any out‐
standing asynchronous operation, although there is at
least one currently outstanding.
EFAULT resultp points to an address outside the address space
of the requesting process. See NOTES.
EINVAL There are not any outstanding requests to cancel.

EFAULT only if it is detected by the application process.
