NAME

      aio_error - retrieve error status of asynchronous I/O operation (REAL‐
      TIME)
 

LIBRARY

      Standard C Library (libc, -lc)
 

SYNOPSIS

      #include <aio.h>
 
      int
      aio_error(const struct aiocb *iocb);
 

DESCRIPTION

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