The returned value itself is meaningless since the timescale depends on the system. Use this only for relative comparisons for benchmarks. A textual description on how the values can be interpreted can be ontained with gavl_benchmark_get_desc
GAVL_PUBLIC const char* gavl_benchmark_get_desc | ( | int | flags | ) |
Get a description about the value returned by gavl_benchmark_get_time.
flags | Flags returned by gavl_accel_supported |
