windows函数是不是就是API函数、两者有什么区别？

windows函数是不是就是API函数、两者有什么区别？

windows函数这个说法理论上不存在的。

windows提供的函数都叫做API.

先新建一个win32 application工程。。

然后在工程中添加源文件。。

然后就可以写代码了。。

记得#include <windows.h>

下面送上一个hello windows。。

#include <windows.h>

lresult callback wndproc (hwnd hwnd, uint message, wparam wparam, lparam lparam);

int winapi winmain (hinstance hinstance,     hinstance hprevinstance,     lpstr lpcmdline,     int icmdshow) {     wndclass wc;     hwnd hwnd;         msg msg;     bool bquit = false;

        wc.style = cs_owndc;     wc.lpfnwndproc = wndproc;     wc.cbclsextra = 0;     wc.cbwndextra = 0;     wc.hinstance = hinstance;     wc.hicon = loadicon (null, idi_application);     wc.hcursor = loadcursor (null, idc_arrow);     wc.hbrbackground = (hbrush) getstockobject (white_brush);     wc.lpszmenuname = null;     wc.lpszclassname = "hellowindows";     registerclass (&wc);

        hwnd = createwindow (     "hellowindows", "hello windows",     ws_caption | ws_popupwindow | ws_visible,     0, 0, 256, 256,     null, null, hinstance, null);

        while (!bquit)     {          if (peekmessage (&msg, null, 0, 0, pm_remove))     {          if (msg.message == wm_quit)     {     bquit = true;     }     else     {     translatemessage (&msg);     dispatchmessage (&msg);     }     }     else     {     sleep (1);     }     }

        destroywindow (hwnd);

    return msg.wparam; }

lresult callback wndproc (hwnd hwnd, uint message,     wparam wparam, lparam lparam) {

    switch (message)     {     case wm_create:     return 0;     case wm_close:     postquitmessage (0);     return 0;

    case wm_destroy:     return 0;

    case wm_keydown:     switch (wparam)     {     case vk_escape:     postquitmessage(0);     return 0;     }     return 0;

    default:     return defwindowproc (hwnd, message, wparam, lparam);     } }
