DRStopwatch provides a simpler API to measure times from applications written in C/C++ to applications for iOS and Mac OS X. This project has two main goals: be simple and be precise.

Note Support for Linux and Apple hardware (iOS and Mac OS X)

Just drag DRStopwatch folder to your project.

To use DRStopwatch you only need to declare a structure Stopwatch and use the following API.

void sw_start(Stopwatch *s);
void sw_stop(Stopwatch *s);
double sw_get_elapsed_milliseconds(Stopwatch *s);
double sw_get_elapsed_seconds(Stopwatch *s);

Warning On Linux you may need to link with the librt library using -lrt.

The support for Objective-C is made of a wrapper around the C/C++ API, the class DRStopwatch. This class provides the following API.

+ (instancetype)stopwatch;
+ (instancetype)stopwatchStartingNow;
- (id)init;
- (void)start;
- (void)stop;
- (double)elapsedTime:(DRTimeOption)option;

Note DRTimeOption can take the values kElapsedTimeSeconds and kElapsedTimeMilliseconds to specified the time unit.
