Standard C Library (libc, -lc)
#include <aio.h> int aio_error(const struct aiocb *iocb);
The aio_error() function 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) is returned. On failure, aio_error() returns -1 and sets errno to indicate the error condition.
The aio_error() function will fail if: [EINVAL] iocb 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_error() is expected to conform to the IEEE Std 1003.2 (“POSIX.2”) standard.
The aio_error function first appeared in FreeBSD 3.0.
