HANDLE CreateFile(
LPCTSTR lpFileName,
DWORD dwDesiredAccess,
DWORD dwShareMode,
LPSECURITY_ATTRIBUTES lpSecurityAttributes,
DWORD dwCreationDisposition,
DWORD dwFlagsAndAttributes,
HANDLE hTemplateFile
);
Parameters
lpFileName
[in] Pointer to a null-terminated string that specifies the name of the object, such as file, COM port, disk device, or console, to create or open.
If *lpFileName is a path, there is a default string size limit of MAX_PATH characters. This limit is related to how the CreateFile function parses paths.
When lpFileName points to a COM port to open, you must include a colon after the name. For example, specify COM1: to open that port. When using IrCOMM, specify COM3:.
在msdn查找CreateFile打开磁盘时对lpFileName的说明不太清楚，特此说明一下，CreateFile打开磁盘时，lpFileName的格式必须为"\\\\.\\C:"(打开C盘)，"\\\\.\\D:"(打开D盘)
程序如下：访问C盘
hFile = CreateFile("\\\\.\\C:",
GENERIC_READ|GENERIC_WRITE,
FILE_SHARE_READ,
NULL,
OPEN_EXISTING,
0,
NULL);
