Re: [Libguestfs] [PATCH 06/10] Rearrange and tidy up code in guestfsd.c

From: Richard Jones <rjones(a)trick.home.annexia.org&gt; This just tidies up the main() function in the daemon. There is no longer a huge fixed-sized buffer used for the kernel command line. Variables are moved closer to where they are used. Some local variables turned out to be unused - these are removed. Finally the part that reads the kernel command line is moved into a separate function. There is only minimal functional change here (it now prints out the kernel command line).

+ char lenbuf[4]; + XDR xdr; + uint32_t len = GUESTFS_LAUNCH_FLAG; + xdrmem_create (&xdr, lenbuf, sizeof lenbuf, XDR_ENCODE); + xdr_uint32_t (&xdr, &len); - if (xwrite (sock, buf, xdr_getpos (&xdr)) == -1) + if (xwrite (sock, lenbuf, 4) == -1)
