[Devel] find_export("append_hf") - usage?

[Daniel Hsueh]

Hello,

I need to add a header to a sip message from within a module.

Instead of fighting with the struct lump mechanism, is it simply easier 
to find the "append_hf" function and call it directly?  And how is 
memory managed for the string passed in?  (My guess is that the caller 
manages its own buffer, and the append_hf code stores its own copy -- 
this is suggested by the usage in modules/osp/sipheader.c and 
modules/alias_db/alookup.c, yes?

(Or if someone wants to help me through the struct lump mechanism, I'll 
try it.)

Thanks!
