-.SH DESCRIPTION
-io_prep_write is a convenicence function for setting up parallel writes.
-
-The first
-.TP
-.IR "iocb->u.c.nbytes = count"
-bytes of the file for which
-.TP
-.IR "iocb->aio_fildes = fd"
-is a descriptor are written from the buffer
-starting at
-.TP
-.IR "iocb->u.c.buf = buf"
-.
-.br
-Writing starts at the absolute position
-.TP
-.IR "ioc->u.c.offset = offset"
-in the file.
-.PP
-This function returns immediately . To schedule the operation, the
-function
-.IR io_submit
-must be called.
-.PP
-Simultaneous asynchronous operations using the same iocb produce
-undefined results.
