Build

To build a static and dynamic library of CPUTime on Windows, Linux or Mac OSX,

1. Download premake 5 and make it available in your path

2. Run the following from the command line

    git clone https://github.com/centaurean/cputime.git
    cd cputime/build
    premake5 gmake
    make

or alternatively, on Windows for example :

    premake5.exe vs2017
    msbuild CPUTime.sln

If msbuild.exe is not available in your path, just launch Visual Studio by double clicking on CPUTime.sln and build the library inside the IDE.

Quick start

#include "cputime_api.h"

cputime_chronometer chrono;
cputime_chronometer_start(&chrono);
// Do something
double lap = cputime_chronometer_lap(&chrono);
// Do something else
double elapsed = cputime_chronometer_stop(&chrono);

// At any time, if needed, it's possible to get a timeval structure containing the total elapsed usermode time
struct timeval current_total_usertime = cputime_get_current_total_usertime();
