[Gambas-user] error calling external function from c library

[Marcos Antonio Pandolfo Jr]

Benoit

    Thanks soo much for your help.... I attach a example writed in C that
contains the call of some functions in this library. The function that I
have problem is the ContinuaFuncaoSiTefInterativo... I believe that you
seeing this example you resolve the problem.... I dont have experience to
visualize the solution..... If you need I can send the libraries.... The
documentation of these libraries are writted in portugues and I think that
will be useless to you.

Regards
