    13 // Description:

    14 // e32test\dll\t_path.cpp

    15 // Overview:

    16 // Test imported DLL path search order.

    17 // API Information:

    18 // None (implicit searching when loading an executable)

    19 // Details:

    20 // - t_pathdll1 and t_pathdll2 both export the same function which returns 1

    21 // 2 respectively.

    22 // - Run t_path2 (linked to t_pathdll1) and check return value from DLL - should

    23 // be 1.

    24 // - Copy t_pathdll2 to C: and rename to t_pathdll1 - it should now be loaded 

    25 // instead.

    26 // - Run t_path2 again and check return value from DLL - should be 2.

    27 // Platforms/Drives/Compatibility:

    28 // Not on emulator.

    29 // Assumptions/Requirement/Pre-requisites:

    30 // Failures and causes:

    31 // Base Port information:
