GSX-86 Library For Microsoft & OpenWatcom C
Access GSX-86 Routines Easily from C!
Research's Graphics System Extension (GSX) provides a unified graphics
API across a range of hardware. Digital Equipment Corporation,
with their DEC Rainbow 100 GSX-86 distribution, provided a C library to
without the hassle of assembly programming. However, the
library was available only for Mark Williams C under CP/M-86/80.
A later port by some independent DEC employees provided the same
library for the now-obscure Computer Innovations C compiler under
MS-DOS along with source.
Now that MS-DOS library is available for Microsoft and OpenWatcom C compilers after some minor
changes to the assembly language interface and the C wrapper routines.
The source code has been cleaned up, and it is now tested and
available for use with the Microsoft C 5.1 compiler under MS-DOS and the current OpenWatcom C/C++ compiler with a 16-bit DOS target.
The library provides high-level interfaces for GSX-86 routines,
including drawing primitives, console input/output, graphic font
handling, and graphic inquiry functions. The library includes the
original documentation provided by DEC with their GSX-86
Complete source code, an intermediate compiled assembly object file,
and a self-contained medium memory model library are included in the
distribution. Sample source code is also available from the
download page. Give the new library a try!
