Problem addressing arrays from C routines running OSF [message #5657]

I am writing a program which have to access some routines writen
i C. These routines

have the form somewhat like this:

---- C -----

int routine(int argc, void *argv[])
{
short *ptr = (short *)argv[0];

// do som operations on the array addressed using <ptr>

return TRUE;
}

---- IDL -----
; array = intarr(512, 512);
function routine, array
return, call_external('routine.so', 'routine', array)
end

This method of addressing an array works under Solaris, SGI Irix
and Windows
but not under OSF/1 on a DEC alpha workstation.

I think that the problem is that IDL tries to send a 32 bit
pointer, and the
C program expects a 64 bit pointer ( a good way to create chaos
:-) )

Any suggestions on how to solve this problem?
