    13 // Description:

    14 // e32test\debug\t_schedhook.cpp

    15 // Overview:

    16 // Test the device hook functionality.

    17 // API Information:

    18 // RBusLogicalChannel, DLogicalDevice

    19 // Details:

    20 // - Load the specified logical driver dll and check the return value

    21 // is as expected. Create the logical channel for the current thread

    22 // and check the return value as KErrNone.

    23 // - Install the scheduler hook and check it is installed successfully.

    24 // - Enable scheduler callback, setup test threads, test the scheduler hook

    25 // before thread resume and after resume is as expected.

    26 // - Perform some context switching and check rescheduler count is as expected.

    27 // - Disable scheduler callback, perform some context switching and check

    28 // thread rescheduler count is as expected.

    29 // - Re-enable scheduler callback, perform some context switching and check

    30 // thread rescheduler count is as expected.

    31 // - Remove schedule hook and check it is successfully removed. perform some

    32 // context switching and check thread rescheduler count is as expected.

    33 // - Check exception during context switching, user mode interrupt, WFAR,

    34 // exec call are as expected.

    35 // - Uninstall scheduler hook and check it is as expected.

    36 // Platforms/Drives/Compatibility:

    37 // Hardware (Automatic).

    38 // Assumptions/Requirement/Pre-requisites:

    39 // Failures and causes:
