what actually uses xdr_mem.c?

I would not rely on the binaries to find out, which programs make use of the
above functions. That's one of the advantages of an open source os ;-)

Something like

   cd /usr/src
   grep -rl 'xdrmem_getlong_aligned' *

will print all the files that contain the string 'xdrmem_getlong_aligned'. Based
on the path name of those file, you will be able to find out which programs use
the xdr* functions.

HTH,
 Simon
