NAME
       io_submit - Submit asynchronous I/O blocks for processing


SYNOPSIS
       #include <linux/aio.h>

       long io_submit (aio_context_t ctx_id, long nr, struct iocb **iocbpp);


DESCRIPTION
       io_submit()  queues  nr  I/O  request  blocks for processing in the AIO
       context ctx_id. iocbpp should be an array of  nr  AIO  request  blocks,
       which will be submitted to context ctx_id.


RETURN VALUE
       io_submit()  returns the number of iocbs submitted and 0 if nr is zero.


ERRORS
       EINVAL The aio_context specified by ctx_id is invalid.  nr is less than
              0.  The  iocb  at *iocbpp[0] is not properly initialized, or the
              operation specified is invalid for the file  descriptor  in  the
              iocb.

       EFAULT One of the data structures points to invalid data.

       EBADF  The file descriptor specified in the first iocb is invalid.

       EAGAIN Insufficient resources are available to queue any iocbs.

       ENOSYS io_submit() is not implemented on this architecture.


CONFORMING TO
       io_submit()  is  Linux specific and should not be used in programs that
       are intended to be portable.


VERSIONS
       The asynchronous I/O system calls first appeared in Linux  2.5,  August
       2002.


SEE ALSO
       io_setup(2), io_destroy(2), io_getevents(2), io_cancel(2).


NOTES
       The asynchronous I/O system calls were written by Benjamin LaHaise.
