# NAME

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

# LIBRARY

POSIX Real-time Library (librt, -lrt)

# 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). 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 aiocb argument does not reference an outstanding asynchronous I/O request.

# SEE ALSO

# STANDARDS

The `aio_error`() system call is expected to conform to the IEEE Std 1003.1-2001 (“POSIX.1”) standard.

# HISTORY
