64 * sets this variable such that a driver can evaluate this variable
65 * to determine if an assert occurred.
70 * This variable allows the assert functionality to be changed for testing
71 * such that it does not wait infinitely. Use the debugger to disable the
72 * waiting during testing of asserts.
