[streaming] Re: vls-0.5.3 on solaris9 with gcc3.3

Thu Oct 2 01:16:16 CEST 2003

The significance of const is that the function will not touch the 
struct. Often coders are sloppy in specifying const when appropriate. It 
is actually a valuable construct to allow the compiler to recognize 
logic errors. If it is just a redefine issue just comment out vls 
declare. From your description it seemed that vls perhaps also 
instaniated the function, if so you most certainly do not want that, but 
rather the system function.
