How can I reliably position the file pointer at the beginning of the second line for reading (and writing) regardless of the varying length of the first status line.

However, I tried reading the first line (using fscanf) and the pointer was NOT positioned at the beginning of the second line. In fact it was not on the 2nd line at all. Did you mean I should use "fread"? Can you explain please.

char szLine[128];
fscanf(pFile, "%[^\n]\n", szLine);

How can we rotate a 2d line in 3d to get a cone or can anyone point me to any useful resource on this (Open GL).

glBegin(GL_LINES);
  glVertex3f(0.0f, 0.0f, 0.0f);
  glVertex3f(50.0f, 50.0f, 50.0f);
glEnd();

glPushMatrix();
glRotatef(30.0,0.0f,1.0f,0.0f);
