Windows equivalent for system configuration directory

Question

I am developing an application in the Ruby CLI, and I would like to allow setting on Unix via standard cascade configuration file /etc/appnamerc, ~/.appnamerc. However, the application is also intended to run in a Windows environment, and I'm not sure where you can place a file of the type /etc/appnamerc(it C:\windows\system32\etc\driversdoesn't seem like it will be the right place). In addition, any scheme that I decide to search for a system configuration file must also consider different versions of Windows, i.e. C:\Usersand C:\Documents and Settings. As for the user-specific configuration, I'm also not sure where to look for the application for the configuration file for a specific user, and what is the standard naming convention for something like that.

Answer 1

What you are looking for is the SHGetKnownFolderPath function (or - on older versions of Windows - the SHGetFolderPath function ).

While Windows has conventions that these paths and where they are located are completely dependent on version, configuration, and other factors, so hard-coded folder names are a bad idea. However, the above was the function of getting these "special" folder locations from the very beginning.

The main argument of these functions is either KNOWNFOLDERID , or CSIDL , which indicates which folder you want.

char szBuffer[1024];

// get the common application data folder
::SHGetSpecialFolderPath(0, szBuffer, CSIDL_COMMON_APPDATA, false);
