这个常数"UNITS"的值

Question

我复制了互联网的代码源,它有一个恒定的"UNITS".这个常数的价值是多少？我想找到但没找到.

见http://graph-studio-next.googlecode.com/svn-history/r169/trunk/baseclasses/pullpin.cpp

 m_tDuration = llTotal * UNITS;

Answer 1

根据:http://graph-studio-next.googlecode.com/svn/!svn/bc/169/trunk/baseclasses/reftime.h:

const LONGLONG NANOSECONDS = (1000000000); // 10 ^ 9
const LONGLONG UNITS = (NANOSECONDS / 100); // 10 ^ 7
