CLOCKS_PER_SEC

钟[医]每[医]证交会

Defined in header ​​
#define CLOCKS_PER_SEC /*implementation defined*/​​

展开为表达式%28，不一定是类型的编译时常数%29。std::clock_t等于每秒时钟滴答数。std::clock()...

注记

POSIX定义CLOCKS_PER_SEC的实际精度为一百万。std::clock()...

另见

clockreturns raw processor clock time since the program is started (function)
