Then in principle only a single line needs editing to change > the naming convention. > > This patchset implements this idiom more completely. The first patch > adds some missing _NAME macros and fixes cases in source files that > should be using the macros. The second patch then changes header > files where the macros should have been used, but weren't. This > required changing the idiom for removing a machine driver function > pointer from MDRV_<FUNCTION>(NULL) to MDRV_<FUNCTION>(0), to avoid > problems with NULL being macro expanded. This actually unifies the > handling of all such cases, as we already had ipt_0 and driver_init_0. > It also required reworking the devtempl.h implementation in a way that > triggered a warning on MSVC about using empty macros, so vconv.c > needed to be updated. The third patch then renames all the _NAME and > _0 macros to verify that all the cases have been covered, so it isn't > intended to be applied. > > ~aa |
