I am working on an opengl example, but I can't seem to get glFrustum to work. It accepts 6 doubles, but I'm not sure where to put these. sprintf has similar issues. This is the only thing i've tried that works:

Code:

         sub   esp,8*6
         movupd   xm0,[@f]
         movupd   [esp],xm0
         movupd   xm0,[@f+8*2]
         movupd   [esp+8*2],xm0
         movupd   xm0,[@f+8*4]
         movupd   [esp+8*4],xm0
         invoke glFrustum
         ret

  @@: GLdouble -0.5,0.5,-0.5,0.5,1.0,10.0

Is there a better way?? Also, if they are floating point arguments, shouldn't they be passed in the fpu?

invoking with "double" works.

Code:

invoke glFrustum,double 1.0,double 555.456,double 879.125.....etc.

that does not compile for me: 'double' is not a defined symbol

You need to include an 'x' version of the macros. e.g.

Code:

include 'win32ax.inc'

I think you need to include win32ax.inc/win32wx.inc for it.

If you don't want to include one of those, I think it would be possible to just copy out the "pushd" macro included in it.
