NAME

aio_error — retrieve error status of asynchronous I/O operation (REALTIME)

LIBRARY

Standard C Library (libc, -lc)

SYNOPSIS

#include <aio.h>

int
aio_error(const struct aiocb *aiocbp);

DESCRIPTION

The aio_error() system call returns the error status of the asynchronous I/O request associated with the structure pointed to by aiocbp.

RETURN VALUES

If the asynchronous I/O request has completed successfully, aio_error() returns 0. If the request has not yet completed, EINPROGRESS is returned. If the request has completed unsuccessfully, the error status is returned as described in read(2), write(2), or fsync(2) is returned. On failure, aio_error() returns -1 and sets errno to indicate the error condition.

ERRORS

The aio_error() system call will fail if:

[EINVAL]

The aiocbp argument does not reference an outstanding asynchronous I/O request.

STANDARDS
