AIO_ERROR

Linux Programmer's Manual (3)
2013-07-04
 

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. (See aio(7) for a description of the aiocb structure.)  

RETURN VALUE

This function returns one of the following:
*
EINPROGRESS, if the request has not been completed yet.
*
ECANCELED, if the request was canceled.
*
0, if the request completed successfully.
*
A positive error number, if the asynchronous I/O operation failed. This is the same value that would have been stored in the errno variable in the case of a synchronous read(2), write(2), fsync(2), or fdatasync(2) call.
 

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.
ENOSYS
aio_error() is not implemented.
