I have need of Add1ResMenu(), a function which would behave
like AddResMenu(), but only search the current rsrc file.
Here`s my current attempt:

void Add1ResMenu(MenuHandle theMenu, ResType theType){
    short    i;
    short    resCount;
    
    resCount = Count1Resources(theType);
    for(i=1; i<=resCount; ++i){
        short    resId;
        ResType  resType;
        Str255   resName;
        Handle   resHandle;
        
        resHandle = Get1IndResource(theType,i);
        if(resHandle){
            GetResInfo(resHandle,&resId,&resType,resName);
            if(resName[0]>0 && resName[1]!='.' && resName[1]!='%'){
                AppendMenu(theMenu,resName);
            }
        }
    }
} 

The problem is that I'd like to call ReleaseResource on resources that
haven`t already been gotten (i.e. someone previously called GetResource
or GetNamedResource on it). But how do I know if a resource has already
been gotten?

And while your at it. There is one more resouce file question I have.
Is there any way I can get a list of all the currently opened resource
files and/or check if a particular resource file is already open.

Please respond via email if possible.
