SolvedC++ Duplicating Cvars

yeah, I acquired all the headers needed to do the shit, now i need to know how you duplicate a cvar. i doubt i'm going to get any useful help but it's worth a shot.

cvars are useless, dont touch them

ConVar *cv = new ConVar(...)
cv->m_pszName = toreplace->m_pszName
// stuff you want to do
toreplace->m_pszName = "newname"
/* or */
cvar->UnregisterConvar(toreplace)
cvar->RegisterConvar(cv)

or something i don't remember
