// Contents: implementation for CStrLengthCmdlineObj
//
// Synoposis: Encapsulates a command line switch which takes an
// length restricted string, eg: /password:<value>, where the
// value must be between MINPASSWORD and MAXPASSWORD in
// length
//
// Classes: CStrLengthCmdlineObj
//
// History: 12/27/91 Lizch Created
// 04/17/92 Lizch Converted to NLS_STR
// 09/09/92 Lizch Changed SUCCESS to NO_ERROR
// 09/18/92 Lizch Precompile headers
// 10/18/93 DeanE Converted to WCHAR

// Synoposis: Stores the specified value, eg "lizch" from

//

//
// Arguments: [nszArg] - the string following the switch on the
// command line. Excludes the equator (eg.
// ':' or '=' ), if any.
//
// Returns: CMDLINE_NO_ERROR or CMDLINE_ERROR_INVALID_VALUE
