Measuring time with a resolution of microseconds in C++?

Question

I\'m looking for a way to measure microsecs in C++/Windows.

I read about the \"clock\" function, but it returns only milliseconds...
Is there a way to do it?

Answer 1

(since no-one has mentioned a pure c++ approach yet),

as of c++11:

#include 
std::chrono::duration_cast(std::chrono::system_clock::now().time_since_epoch())

gets you the number of microseconds since 1970-01-01, and a port of php's microtime(true) api would be

#include 
double microtime(){
    return (double(std::chrono::duration_cast(std::chrono::system_clock::now().time_since_epoch()).count()) / double(1000000));
}

gets you the number of seconds since 1970-01-01 with microsecond precision
