Overview

cc65 is based on a native C compiler that was originally adapted for the Atari 8-bit computers by John R. Dunning in 1989, which originated as a Small-C descendant. It has several extensions, and some of the limits of the original Small C compiler are gone. The toolkit has largely been expanded by Ullrich von Bassewitz and other contributors. The actual cc65 compiler, a complete set of binary tools (assembler, linker, etc.) and runtime library are under a license identical to zlib's. The compiler itself comes close to ANSI C compatibility, while C library features depend on the target platform's hardware. stdio is supported on many platforms, as is

Supported API

static

*conio (text-based console I/O non-scrolling) *dio (block-oriented disk I/O bypassing the file system)

dynamic

*em (expanded memory, used for all kinds of memory beyond the 6502's 64K barrier, similar EMS) *joystick (relative input devices) *mouse (absolute input devices) *serial (communication) *tgi (2D graphics primitives inspired by BGI) Note: For static libraries, "Yes" means the feature is available. For dynamic libraries, the columns list the number of available drivers.
