NAME

       io_prep_pwrite - Set up iocb for asynchronous writes

SYNOPSYS

       #include <errno.h>

       #include <libaio.h>

       inline void io_prep_pwrite(struct iocb *iocb, int fd, void *buf, size_t count, long long offset)
       "

       struct iocb {
            void      *data;
            unsigned  key;
            short          aio_lio_opcode;
            short          aio_reqprio;
            int       aio_fildes;
       };

DESCRIPTION

       io_prep_write  is  a  convenicence  function  for  setting  up parallel
       writes.

       The first

       iocb->u.c.nbytes = count
              bytes of the file for which

       iocb->aio_fildes = fd
              is a descriptor are written from the buffer starting at

       iocb->u.c.buf = buf
              Writing starts at the absolute position

       ioc->u.c.offset = offset
              in the file.

       This function returns immediately .  To  schedule  the  operation,  the
       function io_submit must be called.

       Simultaneous  asynchronous  operations  using  the  same  iocb  produce
       undefined results.

RETURN VALUES

       None

ERRORS
