      Description

      The standard, predefined macros, such as _FILE and LINE_, are primarily intended for use by the implementation, and changing them could result in undefined behavior.

      This rule checks that the following predefined macros are not defined, undefined, or redefined: assert, errno, _FILE, LINE, TIME, DATE, TIMESTAMP, COUNTER, INCLUDE_LEVEL, BASE_FILE_, and _Pragma.

      Noncompliant Code Example 

      #undef __LINE__

      See
