FreeBSD 6.2 manual page repository

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>
      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) is returned.
      On failure, aio_error() returns -1 and sets errno to indicate the error


      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.

Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
