Module Name:

Abstract:
This module is responsible for Atlas functionality common to all drivers.

Routine Description:
This routine will register the passed in value name and its associated value for Atlas to find. In addition, we will create a symbolic link to a name which is accessible for Atlas to open and exchange information.
Arguments:
DeviceName - pointer to unicode string to use when creating a symbolic link. It is assumed this device name is all ready created and ready to have symbolic links created.
ValueName - pointer to unicode string to be used as the registry value name.
Value - pointer to unicode string to be used as the value associated with ValueName.
Return Value:
- STATUS_SUCCESS if successful
- Error indicating problem
