分享MapViewOfFile为什么只能共享一个字节？
m_user="fgh";
DWORD dwUser;
static HANDLE s_hFileMap=NULL;
s_hFileMap=CreateFileMapping(INVALID_HANDLE_VALUE,NULL,PAGE_READWRITE,0,4*1024,TEXT("MMFSharedData"));
if(s_hFileMap!=NULL)
{
PVOID pView=MapViewOfFile(s_hFileMap,FILE_MAP_READ|FILE_MAP_WRITE,0,0,0);
if(pView!=NULL)
{
AfxMessageBox("ok");
(CString)(LPTSTR)pViewm_user;
m_user=(CString)(LPTSTR)pView;
UnmapViewOfFile(pView);
}
}
CloseHandle(s_hFileMap);
//m_user="f",why?
