GetSystemDirectory
The GetSystemDirectory function retrieves the path of the Windows system directory. The system
directory contains such files as Windows libraries, drivers, and font files.
UINT GetSystemDirectory(
LPTSTR lpBuffer,
| // address of buffer for system directory
| UINT uSize
| // size of directory buffer
| );
|
|
Parameters
lpBuffer
Points to the buffer to receive the null-terminated string containing the
path. This path does not end with a backslash unless the system directory is the
root directory. For example, if the system directory is named WINDOWS\SYSTEM on
drive C, the path of the system directory retrieved by this function is
C:\WINDOWS\SYSTEM.
uSize
Specifies the maximum size of the buffer, in characters. This value should be
set to at least MAX_PATH.
Return Values
If the function succeeds, the return value is the length, in characters, of
the string copied to the buffer, not including the terminating null character. If
the length is greater than the size of the buffer, the return value is the
size of the buffer required to hold the path.
If the function fails, the return value is zero. To get extended error
information, call GetLastError.
Remarks
Applications should not create files in the system directory. If the user is running a shared version
of Windows, the application does not have write access to the system
directory. Applications should create files only in the directory returned by the GetWindowsDirectory 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 » |
