Subject: Re: Help finding a leak

Thanks for your help everything almost works now.  The only problem I
have now is that it seems that there is no to_ptr method in ruby/dl2 so
how do I pass a ptr to a function that takes a string and changes the
string?  I tried using CPtr but I'm not to sure how to use it.

here is the DL extern setup for the function

extern 'ATOM GlobalGetAtomName(ATOM,PVOID,int)'

Here is what I had and it worked with the old DL.

tmp = "".ljust(256,"NO-CHANGE")
z1 = tmp.to_ptr
if(msg == @MessageRequestComplete)
   MyWin32.globalGetAtomName(lparam,z1,255)
   puts z1.to_s
end


Here is what im trying with DL2

tmp = "".ljust(256,"NO-CHANGE")
if(msg == @MessageRequestComplete)
    MyWin32.GlobalGetAtomName(lparam,tmp,255)
    puts tmp
end
