// f32test\demandpaging\t_denyclamp.cpp

// This test suite has a reduced set of the tests in T_CLAMP, to verify

// the behaviour when file clamping is attempted by an invalid user.

// 002 GetDriveLetters() Assign the first drive that matches the required criteria

// 003 Test1() Basic clamp operation

// 004 Test2() Invalid clamp requests

// 005 Test4() Clamp tests for non-writable file system

// 006 Test5() Clamp requests on non-clamping file systems

// This file has a reduced set of tests present in T_CLAMP, to verify

// the behaviour when file clamping is attempted by an invalid user
