Custom CVar system

Code:

	if(head == 0)
	{
		head->name = name;
		head->value = value;
		head->locked = lock;
		return;
	}

Code:

	if(head == 0)
	{
		head = new rCVar;
		head->name = name;
		head->value = value;
		head->locked = lock;
		return;
	}

You could make a constructor for your struct/class to make it easier;

Code:

	if(head == 0)
	{
		head = new rCVar(name, value, lock);
		return;
	}

Ok I updated it, after thinking it over last night. Found a few extra stuff that wasn't needed.

Code:

//setNew: Sets a new cvar if an existing one of the same
// 		  name doesn't exist.
void rCVarEngine::set(const char *name, const char *value,bool lock)
{
	// If we don't have a cvar in our head
	// then set it
	if(head == 0)
	{
		head = new rCVar(name,value,lock);
		return;
		
	}
	// If our current cvarList value hasn't been set
	// then set it...yo
	else if(cvarList == 0)
	{
		cvarList = new rCVar(name,value,lock);
		head->next = cvarList;
		return;
	}

	while(cvarList)
	{
		// If we found an existing CVar
		// then set its value and lock
		// mode
		if(strcmp(cvarList->name, name))
		{
			cvarList->value = value;
			cvarList->locked = lock;
			return;

		}
		// Else if the next in the list is empty
		// Set its new values
		else if(cvarList->next == 0) 
		{

					
			// Add it to the end
			cvarList->next = new rCVar(name,value,lock);
                        return;
		} 
		// If we havn't found the end of the
		// list or if we havn't found a pre-
		// existing cvar, then move to the 
		// next in the list
		else 
		{
				
			cvarList = cvarList->next;
		} 
		
	}
	
}

But it still crashes.

Code:

struct rCVar
{	

	const char *name;
	const char *value;
	bool locked;
	rCVar *next;
	
	// Constructor
	rCVar(const char *cName, const char *cValue, bool cLock)
	{
		name = cName;
		value = cValue;
		locked = cLock;
		next = 0;
	}

};
