Step 7 : ARM 4.0 C Hello World example

Description

We have measured our transaction so we can now stop the application instance:

  1. To stop the application instance we use the arm_stop_application() call. We pass the following parameters:
    1. pointer to application start handle we got from the ARM agent in the previous call to arm_start_application().
    2. ARM_FLAG_NONE - there are no flags defined for this API call.
    3. ARM_BUF4_NONE - it is a simple example, so no optional data is passed.
