External structure definitions

[mister]

I'm using a static library that contains a function whose parameters
include a structure defined within that library. But when I declare
the external function I get errors due to the structure being unknown.
(since it's defined in the library, not my program)

How should I go about telling the linker where the definition for the
structure is? Is it similar to to using extern to declare functions
and variables? Any thoughts?

Thanks,
Nick

Did someone really give you a library without a .h file to include in
your code?

The beauty of header files.


#include "libraryheader.hpp"

int main()
{


}

So it must be within a header file? I'll see about getting the source
for the library so I can find out how the structs are defined and make
my own header file. Thanks

but it seems weird that the lib is provide without related header files
which contain needed type defination,isn't it?

Maybe it's a shit library.
