从 kernel32 调用 winapi 函数

  • 772

没有找到如何调用 QueryPerformanceCounter 函数。像这样试过。给出错误，不知道 BOOL 和 LARGE_INTEGER 是什么。

import core.sys.windows.windows;
import core.sys.windows.w32api;
import core.sys.windows.winbase;
pragma(lib, "kernel32");
extern (Windows)
{
    BOOL QueryPerformanceCounter(LARGE_INTEGER *lpPerformanceCount);
}
void main()
{}
winapi

    import core.sys.windows.winbase;
import core.sys.windows.windef;
import core.sys.windows.windows : QueryPerformanceCounter, QueryPerformanceFrequency;

void main()
{
    LARGE_INTEGER start, finish, freq;
    QueryPerformanceCounter(&start);
    //any long function
    QueryPerformanceCounter(&finish);
    QueryPerformanceFrequency(&freq);
}
