博客-GlobalAlloc的GMEM_FIXED和GMEM_MOVABLE使用

#include <stdio.h> #include <windows.h> #include <tchar.h> int main(int argc, char *argv[]) { HMENU hGlobal; PTSTR pGlobal; TCHAR szBuffer[] = TEXT("Test text"); //GMEM_FIXED hGlobal = GlobalAlloc(GMEM_FIXED, (lstrlen(szBuffer)+1) * sizeof(TCHAR)); pGlobal = GlobalLock(hGlobal); lstrcpy(pGlobal, szBuffer); _tprintf(TEXT("pGlobal和hGlobal%s\n"), pGlobal==hGlobal ? TEXT("相等") : TEXT("不相等")); GlobalUnlock(hGlobal); _tprintf(TEXT("使用句柄当做指针访问的数据为:%s\n"), hGlobal); GlobalFree(hGlobal); //GMEM_MOVABLE hGlobal = GlobalAlloc(GMEM_MOVEABLE, (lstrlen(szBuffer)+1) * sizeof(TCHAR)); pGlobal = GlobalLock(hGlobal); lstrcpy(pGlobal, szBuffer); _tprintf(TEXT("pGlobal和hGlobal%s\n"), pGlobal==hGlobal ? TEXT("相等") : TEXT("不相等")); _tprintf(TEXT("使用句柄当做指针访问的数据为:%s\n"), hGlobal); GlobalUnlock(hGlobal); GlobalFree(hGlobal); return 0; }
