Detailed Description

Tests the option constants of the Classic API.

This test case performs the following actions:

• Validate the non-default option constants.
  • Check that RTEMS_EVENT_ANY is a power of two.
  • Check that RTEMS_NO_WAIT is a power of two.
• Validate the default option constants.
  • Check that RTEMS_DEFAULT_OPTIONS is equal to zero.
  • Check that RTEMS_EVENT_ALL is equal to zero.
  • Check that RTEMS_WAIT is equal to zero.
• Calculate the bitwise or of all non-default option constants.
  • Check that the count of set bits in the calculated value is equal to the count of non-default option constants. Since each non-default option constant is a power of two, this proves that each constant has a unique value.
