"Obviously"?...  Well, yes, the

   draw in opengl colored points

is not C++ code (unless those are names of some macros that, when 
substituted, produce compilable C++ code).  Try replacing it with, say,

     printf("point: %d %d\n", laty, lonx);

and see if it "works" then.

The loops look OK, *given* certain assumptions.  But my assumptions can 
be totally different from yours.  State yours, and we can verify.
