GetShortPathName
The GetShortPathName function obtains the short path form of a specified input path.
DWORD GetShortPathName(
LPCTSTR lpszLongPath,
| // points to a null-terminated path string
| LPTSTR lpszShortPath,
| // points to a buffer to receive the null-terminated short form of the path
| DWORD cchBuffer
| // specifies the size of the buffer pointed to by lpszShortPath
| );
|
|
Parameters
lpszLongPath
Points to a null-terminated path string. The function obtains the short form
of this path.
lpszShortPath
Points to a buffer to receive the null-terminated short form of the path
specified by lpszLongPath.
cchBuffer
Specifies the size, in characters, of the buffer pointed to by lpszShortPath.
Return Values
If the function succeeds, the return value is the length, in characters, of
the string copied to lpszShortPath, not including the terminating null character.
If the function fails due to the lpszShortPath buffer being too small to contain the short path string, the return value is
the size, in characters, of the short path string. You need to call the
function with a short path buffer that is at least as large as the short path string.
If the function fails for any other reason, the return value is zero. To get
extended error information, call GetLastError.
Remarks
When an application calls this function and specifies a path on a volume that
does not support 8.3 aliases, the function fails with ERROR_INVALID_PARAMETER
if the path is longer than 67 bytes.
The path specified by lpszLongPath does not have to be a fully qualified path or a long path. The short form may
be longer than the specifed path.
If the specified path is already in its short form, there is no need for any
conversion, and the function simply copies the specified path to the buffer for
the short path.
You can set lpszShortPath to the same value as lpszLongPath; in other words, you can set the buffer for the short path to the address of
the input path string.
You can obtain the long name of a file from the short name by calling the FindFirstFile function.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
