From: Antonio Ospite Date: Tue, 17 Dec 2013 22:55:21 +0000 (+0100) Subject: Add a fps_meter_ prefix to macros X-Git-Url: https://git.ao2.it/experiments/fps-meter.git/commitdiff_plain/refs/heads/master Add a fps_meter_ prefix to macros This plays more nicely when including files where other functions with the same names are defined. --- diff --git a/fps-meter.c b/fps-meter.c index c1a245f..2d9ea6b 100644 --- a/fps-meter.c +++ b/fps-meter.c @@ -27,7 +27,7 @@ int main(void) fps_meter_init(&stats); while (1) { /* simulate some workload of about 60fps */ - dbg("Doing some work, which takes about %d ns", NSEC_PER_SEC / 60); + fps_meter_dbg("Doing some work, which takes about %d ns", NSEC_PER_SEC / 60); tmp.tv_sec = 0; tmp.tv_nsec = NSEC_PER_SEC / 60; clock_nanosleep(CLOCK_MONOTONIC, 0, &tmp, NULL); diff --git a/fps-meter.h b/fps-meter.h index c756ab6..4b72180 100644 --- a/fps-meter.h +++ b/fps-meter.h @@ -25,19 +25,19 @@ #include #ifdef DEBUG -#define dbg(...) \ +#define fps_meter_dbg(...) \ do { \ printf(__VA_ARGS__); \ printf("\n"); \ fflush(stdout); \ } while(0) #else -#define dbg(...) do {} while(0) +#define fps_meter_dbg(...) do {} while(0) #endif #define NSEC_PER_SEC 1000000000 -#define timespecsub(a, b, result) \ +#define fps_meter_timespecsub(a, b, result) \ do { \ (result)->tv_sec = (a)->tv_sec - (b)->tv_sec; \ (result)->tv_nsec = (a)->tv_nsec - (b)->tv_nsec; \ @@ -60,20 +60,20 @@ static void fps_meter_init(struct fps_meter_stats *stats) memset(stats, 0, sizeof(*stats)); clock_gettime(CLOCK_MONOTONIC, &stats->time_start); - dbg("Init time: s: %ld, ns: %ld", stats->time_start.tv_sec, stats->time_start.tv_nsec); + fps_meter_dbg("Init time: s: %ld, ns: %ld", stats->time_start.tv_sec, stats->time_start.tv_nsec); } static void fps_meter_update(struct fps_meter_stats *stats) { struct timespec elapsed; - dbg("Start time: s: %ld, ns: %ld", stats->time_start.tv_sec, stats->time_start.tv_nsec); + fps_meter_dbg("Start time: s: %ld, ns: %ld", stats->time_start.tv_sec, stats->time_start.tv_nsec); clock_gettime(CLOCK_MONOTONIC, &stats->time_end); - dbg("End time: s: %ld, ns: %ld", stats->time_end.tv_sec, stats->time_end.tv_nsec); + fps_meter_dbg("End time: s: %ld, ns: %ld", stats->time_end.tv_sec, stats->time_end.tv_nsec); - timespecsub(&stats->time_end, &stats->time_start, &elapsed); - dbg("Elapsed s: %ld ns: %ld", elapsed.tv_sec, elapsed.tv_nsec); + fps_meter_timespecsub(&stats->time_end, &stats->time_start, &elapsed); + fps_meter_dbg("Elapsed s: %ld ns: %ld", elapsed.tv_sec, elapsed.tv_nsec); stats->frames++; stats->nsecs += (elapsed.tv_sec * NSEC_PER_SEC + elapsed.tv_nsec);
