// dmtinputCreateDeviceList
//
// Creates a linked list of DirectInputDevice8A objects. Either enumerates
// suitable or all joystick/gamepad devices.
//
// NOTE: The actual work of adding a node to the list is performed by the
// dmtinputEnumDevicesCallback() function. This function exists merely to
// present a consistant look & feel with the rest of the list creation
// functions used in this app.
//
// Parameters:
//
// Returns: HRESULT
//
// History:
// 08/27/1999 - davidkl - created
// 08/30/1999 - davidkl - moved & renamed
// 10/26/1999 - davidkl - added axis range setting
// 10/27/1999 - davidkl - house cleaning
// 02/21/2000 - davidkl - added hwnd and call to dmtinputGetRegisteredMapFile
