Adjusted include file extension to ca65 practice. 2018-02-23 15:36:05 +00:00			`.include "../inc/common.inc"`
Introduced C interface to IP65. The IP5 usage of ld65 segments and zeropage variables was made compatible with cc65 C programs already a while ago. This commit is the next logical step which is to introduce the actual C interface to IP65. IP65 for C programs shares the the ip65.lib / ip65_tcp.lib with IP65 for assembler programs. However the various libraries from the 'drivers' are not reused. Instead there's exactly one library for every target named ip65_<target>.lib. Those libraries contain only functions used by ip65.lib / ip65_tcp.lib. TODOs: - Introduce c64_timer.s and atr_timer.s. - Add a C interface to the rest of the IP65 functionality (especially TCP). 2017-11-05 13:28:49 +00:00
