GetAllUsersProfileDirectoryA function (userenv.h)
Retrieves the path to the root of the directory that contains program data shared by all users.
Syntax
USERENVAPI BOOL GetAllUsersProfileDirectoryA(
[out, optional] LPSTR lpProfileDir,
[in, out] LPDWORD lpcchSize
);
Parameters
[out, optional] lpProfileDir
Type: LPTSTR
A pointer to a buffer that, when this function returns successfully, receives the path. Set this value to NULL to determine the required size of the buffer, including the terminating null character.
[in, out] lpcchSize
Type: LPDWORD
A pointer to the size of the lpProfileDir buffer, in TCHARs.
If the buffer specified by lpProfileDir is not large enough or lpProfileDir is NULL, the function fails and this parameter receives the necessary buffer size, including the terminating null character.
Return value
Type: BOOL
TRUE if successful; otherwise, FALSE. To get extended error information, call GetLastError.

To obtain the paths of subdirectories of this directory, use the SHGetFolderPath (Windows XP and earlier) or SHGetKnownFolderPath (Windows Vista) function.
Note
The userenv.h header defines GetAllUsersProfileDirectory as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors.
