Синопсис (Synopsis)
#include <aio.h>
int aio_error(const struct aiocb *aiocbp);
Link with -lrt.
Описание (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.)
Возвращаемое значение (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.
Ошибки (Error)
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.
Версии (Versions)
The aio_error() function is available since glibc 2.1.
