Just to clarify my earlier posting;

Whenever I call gopen(), it fails, returning -1.  My Lisp process died
because the C procedure called exit() when gopen() failed.  I have
replaced the exit() call with return and now the C procedure returns
to the Lisp process.

The call to gopen() fails every way I've tried it, which includes calling
it from within a couple different programs, calling it from Lisp directly,
calling it with mode INIT | THREE_D | MODEL_XFORM, and calling it with
mode INIT only.

The call to gopen() generates a different error on a different machine,
namely:

Starbase error 2049: Could not allocate memory.
    Procedure name:      gopen
    File descriptor:     3
    Device file name:    /dev/crtren
    Library location:    HP98721 driver (14)
    System errno:        No such file or directory

Is gopen() trying to allocate memory in a way that can't be done
inside a Lisp process?  In the Lisp manual it mentions that foreign
code should "use malloc to manage memory . . . avoid using sbrk".
Could this have something to do with gopen() failing?

Thank you for your time,
Adam
