problem with core_module on 2.2.x

Hello.

I'm developping my own module, and i have problem with this
line:

core_server_config      *conf =
ap_get_module_config(r->server->module_config,
&core_module)

when compiling:

mod_vhost.c:742: error: `core_server_config' undeclared
(first use in
this function)
mod_vhost.c:742: error: (Each undeclared identifier is
reported only once
mod_vhost.c:742: error: for each function it appears in.)
mod_vhost.c:742: error: `conf' undeclared (first use in
this function)
mod_vhost.c:742: error: `core_module' undeclared (first use
in this function)


Have got any idea how to fix it ?
Or what is wrong ?

Thanks
AK

Don't do that: you're breaking modularity, and going
outside the
API (which means a future update could break your module).

Use the public APIs (available from the headers in /include/
) instead.

Hello.

ok. So i will describe my problem...
I'm developping mod_vhost module (http://kwiatek.eu.org
/mod_vhost).

Now i wan't to add function to set env variable
DOCUMENT_ROOT prior to document_root get from virtual
database.

Only way i've found is to user core_module config and set

conf->ap_document_root.

I there any other way ?

I've tried with:

apr_table_set(r->subprocess_env,
"DOCUMENT_ROOT", apr_pstrdup(r->pool,filter))

but i doesn't work.

Thanks
