    NAME

    
    
    aio_suspend
    
     - suspend until asynchronous I/O operations or timeout complete (REALTIME)
    
     
    

    LIBRARY

    Lb libc
    
     
    

    SYNOPSIS

       #include <aio.h>
    int aio_suspend (const struct aiocb * const iocbs[] int niocb const struct timespec * timeout);
     

    DESCRIPTION

    The aio_suspend ();
    system call suspends the calling process until at least one of the specified asynchronous I/O requests have completed, a signal is delivered, or the Fa timeout has passed.

    The Fa iocbs argument is an array of Fa niocb pointers to asynchronous I/O requests. Array members containing null pointers will be silently ignored.

    If Fa timeout is not a null pointer, it specifies a maximum interval to suspend. If Fa timeout is a null pointer, the suspend blocks indefinitely. To effect a poll, the Fa timeout should point to a zero-value timespec structure.  

    RETURN VALUES

    If one or more of the specified asynchronous I/O requests have completed, aio_suspend ();
    returns 0. Otherwise it returns -1 and sets errno to indicate the error, as enumerated below.  

    ERRORS

    The aio_suspend ();
    system call will fail if:

    Bq Er EAGAIN
    the Fa timeout expired before any I/O requests completed.
    Bq Er EINVAL
    The Fa iocbs argument contains more than AIO_LISTIO_MAX asynchronous I/O requests, or at least one of the requests is not valid.
    Bq Er EINTR
    the suspend was interrupted by a signal.

    STANDARDS

    The aio_suspend ();
    system call is expected to conform to the St -p1003.1 standard.  

    HISTORY

    The aio_suspend ();
    system call first appeared in Fx 3.0 .
