    NAME

    aio_error - get error status of asynchronous I/O operation
     
    

    SYNOPSIS

    #include <aio.h>

    int aio_error(const struct aiocb *aiocbp);

    Link with -lrt.  

    DESCRIPTION

    The aio_error() function returns the error status for the asynchronous I/O request with control block pointed to by aiocbp.  

    RETURN VALUE

    This function returns EINPROGRESS if the request has not been completed yet. It returns ECANCELED if the request was canceled. It returns 0 if the request completed successfully. Otherwise an error value is returned, the same value that would have been stored in the errno variable in case of a synchronous read, write, fsync, or fdatasync request. On error, the error value is returned.  

    ERRORS

    EINVAL
    aiocbp does not point at a control block for an asynchronous I/O request of which the return status (see aio_return(3)) has not been retrieved yet.
     

    CONFORMING TO

    POSIX.1-2001.
