Code examples

The following code example fails the check and will give a warning:

namespace NS1
{
  static int global = 0;
}

namespace NS2
{
  void fn()
  {
    int global; // Non-compliant
  }
}

The following code example passes the check and will not give a warning about this issue:

namespace NS1
{
  int global = 0;
}

namespace NS2
{
  void f1()
  {
    int global; // Non-compliant
  }
}

void f2()
{
  static int global;
}
