Re: [Vala] Name clashes in generated C code

[Aleksander Wabik <alex wabik gmail com>]

Hi,

this sort of problems existed for ever in vala, another example:

// ---- cut here ----
class Test
{
        int one_method()
        {
                return 0;
        }
}

class TestOne
{
        int method()
        {
                return 1;
        }
}
// ---- cut here ----

My way of avoiding such clashes is to know how vala names are
translated to C names ;)

best regards,
AW.
