it depends.

Apache2::ModSSL calls for example a few functions from mod_ssl. Problem is a 
module can be loaded but can also be omitted by the admin. Apache has an 
optional function interface to import functions from another module. The 
following is part of ModSSL.xs. It imports mod_ssl's ssl_is_https() etc.

static void
retrieve_functions(void)
{
  if( is_initialized ) return;
  is_initialized++;
  is_https=APR_RETRIEVE_OPTIONAL_FN(ssl_is_https);
  lookup=APR_RETRIEVE_OPTIONAL_FN(ssl_var_lookup);
  ext_lookup=APR_RETRIEVE_OPTIONAL_FN(ssl_ext_lookup);
}

On the other hand, maybe you have something else in mind, something higher 
level?
