how to use ugluPerspectivex?

[Jacky]

How can I change my floating function of reshape into fixed point?? I don't know how to handle the w/h part...pls help

void reshape (UGWindow uwin, int w, int h)
{
   glViewport (0, 0,  (GLsizei) w, (GLsizei) h);
   glMatrixMode (GL_PROJECTION);
   glLoadIdentity();
   GLfixed temp=(w<<16)/(h);
   //temp<<=16;
   //ugluPerspectivef(80.0, (GLfloat) w/(GLfloat) h, 1.0, 400.0);
   ugluPerspectivex(5262880, temp, 65536, 26214400);
   glMatrixMode(GL_MODELVIEW);
   glLoadIdentity();
   ugluLookAtx(655360, 655360, 655360, 0, 0, 0, 0, 65536, 0);
}

The display is ok if I use ugluPerspectivef, but ugluPerspectivex is not ok even I change the data into fixed value...

void reshape (UGWindow uwin, int w, int h)
{
   glViewport (0, 0,  (GLsizei) w, (GLsizei) h);
   glMatrixMode (GL_PROJECTION);
   glLoadIdentity();

   ugluPerspectivef(80, 1, 1, 400);
   //ugluPerspectivex(5242880, 65536, 65536, 26214400);
   glMatrixMode(GL_MODELVIEW);
   glLoadIdentity();
   ugluLookAtx(655360, 655360, 655360, 0, 0, 0, 0, 65536, 0);
}
