NAME
aioerror - get error status of asynchronous I/O operation SYNOPSIS
#include
int aioerror(const struct aiocb *aiocbp); Link with -lrt. DESCRIPTION The aioerror() 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 aioreturn(3)) has not been retrieved yet. ENOSYS aioerror() is not implemented. VERSIONS The aioerror() function is available since glibc 2.1.
