AIO_ERROR(3P)		   POSIX Programmer's Manual		 AIO_ERROR(3P)

       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the	 corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.

       aio_error - retrieve errors status for an  asynchronous	I/O  operation

       #include <aio.h>

       int aio_error(const struct aiocb *aiocbp);

       The  aio_error() function shall return the error status associated with
       the aiocb structure referenced by the aiocbp argument. The error status
       for  an asynchronous I/O operation is the errno value that would be set
       by the corresponding read(), write(),   fdatasync(),  or fsync() opera‐
       tion.  If  the  operation  has not yet completed, then the error status
       shall be equal to [EINPROGRESS].

       If the asynchronous I/O operation has completed	successfully,  then  0
       shall  be  returned. If the asynchronous operation has completed unsuc‐
       cessfully, then the error status, as  described	for  read(),  write(),
       fdatasync(),   and fsync(), shall be returned.  If the asynchronous I/O
       operation has not yet completed, then [EINPROGRESS] shall be returned.

       The aio_error() function may fail if:

       EINVAL The aiocbp argument does not refer to an asynchronous  operation
	      whose return status has not yet been retrieved.

       The following sections are informative.


       The  aio_error()	 function is part of the Asynchronous Input and Output
       option and need not be available on all implementations.
