NAME

       iob_new - create new I/O batch

SYNTAX

       #include <iob.h>

       io_batch* iob_new(int hint_entries);

DESCRIPTION

       iob_new  creates  a  new  I/O  batch  with enough space allocated for hint_entries entries
       (buffers or files).  This is purely a performance hint, if you are unsure just pass 1.

       You can add buffers, strings and files to an I/O batch and then send it all at once  using
       iob_send.

       The benefit of the I/O batch API is that it exploits platform specific APIs like FreeBSD's
       sendfile.  The file contents will always be sent  in  a  way  that  allows  the  operating
       systems  to  perform  zero  copy  TCP,  and  the  buffers will always be sent using as few
       syscalls as possible and avoiding unnecessary copying (using writev).

RETURN VALUE

       iob_new returns a pointer to  an  I/O  batch  data  structure.   If  there  was  a  memory
       allocation error, it returns NULL instead.
