The error status for an asynchronous I/O operation is the \fBerrno\fR value that would be set by the corresponding \fBread\fR(2), \fBwrite\fR(2), or \fBfsync\fR(3C) operation. If the operation has not yet completed, then the error status will be equal to \fBEINPROGRESS\fR. .SH RETURN VALUES .sp .LP If the asynchronous I/O operation has completed successfully, then \fB0\fR is returned. If the asynchronous operation has completed unsuccessfully, then the error status, as described for \fBread\fR(2), \fBwrite\fR(2), and \fBfsync\fR(3C), is returned. If the asynchronous I/O operation has not yet completed, then \fBEINPROGRESS\fR is returned. .SH ERRORS .sp .LP The \fBaio_error()\fR function may fail if: .sp .ne 2 .mk .na \fB\fBEINVAL\fR\fR .ad .RS 10n .rt The \fIaiocbp\fR argument does not refer to an asynchronous operation whose return status has not yet been retrieved. .RE .SH USAGE .sp .LP The \fBaio_error()\fR function has a transitional interface for 64-bit file offsets. See \fBlf64\fR(7). .SH EXAMPLES .LP \fBExample 1\fR The following is an example of an error handling routine using the \fBaio_error()\fR function. .sp .in +2 .nf #include <aio.h> #include <errno.h> #include <signal.h> struct aiocb my_aiocb; struct sigaction my_sigaction; void my_aio_handler(int, siginfo_t *, void *); \|.\|.\|. my_sigaction.sa_flags = SA_SIGINFO; my_sigaction.sa_sigaction = my_aio_handler; sigemptyset(&my_sigaction.sa_mask); (void) sigaction(SIGRTMIN, &my_sigaction, NULL); \|.\|.\|. my_aiocb.aio_sigevent.sigev_notify = SIGEV_SIGNAL; my_aiocb.aio_sigevent.sigev_signo = SIGRTMIN; my_aiocb.aio_sigevent.sigev_value.sival_ptr = &myaiocb; \|.\|.\|.
