Question

I embed CLIPS into C Language. I want to get the facts and print them to the screen when use Facts() in the main.c it returns "Logical name ��[�� was not recognized by any routers" the code is

main()
{
    char *Facts;
    char str[10];
    InitializeEnvironment();
    Load("my.clp");
    Reset();
    Facts(Facts,NULL,-1,-1,-1);
    Run(-1L);

}

I don't known how to solve it

Answer 1

You need to specify a logical name in the call to Facts:

Facts("stdout",NULL,-1,-1,-1);

You're currently passing in an uninitialized variable.
