Setting temporary file path

[Vinaya]

Hi, I have an application which uses 3 custom DLL. I want to create an additional DLL with method which sets the path of the temporary files created (from the application as well as the other DLLs) to a specified path rather than the system temp file path. If this method of the new DLL is not called in the application, the application can use the system temp path for creating temporary files. I tried using '_putenv()' for setting the environment variable 'TMP' with the new path for temp files, in my new DLL and then calling it from my application. But this does not change the path where the temp files from the DLL are created. It is affecting only the temporary files created from the application. I use the GetTempPath() API to get the temp path. Is there any other method to change the temporary file path. I need the new temp path to affect the methods of all the DLLs. Pls help. Thanks Vini

The only way I know of is to update the values in the HKEY_CURRENT_USER\Environment key.
