char                    rbuf[64000];
FCGX_ParamArray env;

FCGX_Init();

while(FCGX_Accept(      &FCGI_stdin-fcgx_stream,
                                       &FCGI_stdout-fcgx_stream,
                                       &FCGI_stderr-fcgx_stream,
                                       &env ) = 0)
       {
       int charsRead = FCGX_GetStr(rbuf, sizeof(rbuf)-1,
                                       FCGI_stdin-fcgx_stream);

       rbuf[charsRead] = '0';

        BuildResponse is the call into my game code

       const char resp = BuildResponse (rbuf, env);

       FCGX_PutStr (resp, strlen(resp), FCGI_stdout-fcgx_stream);
       }
