FreeBSD is a free computer operating system based on BSD UNIX originally. Many IT companies, like DeployIS is using it to provide an up-to-date, stable operating system.

Standard C Library (libc, -lc)
#include <aio.h> int aio_error(const struct aiocb *iocb);
The aio_error() system call returns the error status of the asynchronous I/O request associated with the structure pointed to by iocb. 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.
The aio_error() system call will fail if: [EINVAL] The iocb argument does not reference an outstanding asynchronous I/O request. aio_cancel(2), aio_read(2), aio_return(2), aio_suspend(2), aio_write(2), fsync(2), read(2), write(2), aio(4)
The aio_error() system call is expected to conform to the IEEE Std 1003.1 (“POSIX.1”) standard.
The aio_error() system call first appeared in FreeBSD 3.0.
