Cliff et al., I revisited the librt timer given your comment about it. It does indeed track both user and wallclock time uing platform-specific means. It also does its own string printing, but lets ignore that for now. Code is in the various src/librt/timer-*.c per-platform files.
You’re right that it should be in libbu. However, it can’t be moved as-is because it’s designed to use globals and we shouldn’t introduce any more globals to any lib. To move it, we need an api either parallel to or replacing bu_gettime() and bu_utctime(). Fortunately, both those names kind of suck, so I’m thinking we just design a better replacement api. The difficulty is that the current bu timer is really simple: int64_t start = bu_gettime(); … printf(“elapsed is %lf\n”, bu_gettime() - start); The bu timer says its supposed to be a wallclock timer, which means it might be wrong on Windows due to the timer being used — I’ll check on that. The only way I can see keeping any new usage that simple, **without introducing a whole other function**, is to have bu_gettime() take bitflags and perhaps return an array of int64_t’s (with the bitflags doubling as indices). Something like this: int64_t start[2], stop[2]; bu_time(&start, sizeof(start), BU_TIME_WALLCLOCK | BU_TIME_CPU); … bu_time(&stop, sizeof(stop), BU_TIME_WALLCLOCK); printf(“elapsed is %lf\n”, stop[BU_TIME_WALLCLOCK] - start[BU_TIME_WALLCLOCK]); There are obviously other options. Anyone have any suggestions? This would probably make a great couple GCI tasks… ;) Cheers!
