At Last an ISO C Binding of GKS

The bindings of GKS and other semantic computer C graphics standards like GKS-3D and PHIGS are long overdue. While GKS was completed in 1985 and GKS-3D (and PHIGS) became an international standard in 1988, none of their C bindings could be standardized, for the simple reason that the C language itself was not a standard. Instead, a host of de facto GKS/C bindings appeared. This paper will give the flavour of the ISO C bind- GKS, GKS-3D, PHIGS, C language binding.
