Print an OID numerically

[Giuseppe M. <g.m...@el...>]

In my sub-agent I want to print an OID in a numerical fashion.
I have "oid *name" and "size_t name_len".

I'm sure there is a function in the Net-SNMP source code like the following:
  print_objid_num( oid *name, size_t name_len );
that prints (on stdout or on a buffer or on a file stream)
  1.2.3.1....


An what about print the OID textual up to enterprises node and numerically 
afterward?
