NAME
       iob_addfile - add file region to I/O batch

SYNTAX

       int iob_addfile(io_batch* b,int64 fd,uint64 off,uint64 n);

DESCRIPTION
       iob_addfile schedules n bytes from the file descriptor fd starting at
       offset off to be written with the I/O batch b.

       You may not close fd before iob_send indicates it is done.

       automatically by iob_reset.
