Code examples

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

#include <stdint.h>
void f ( int32_t )
{
  reinterpret_cast< void (*)( ) >( &f ); // Non-compliant
}

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

#include <stdint.h>
void f ( int32_t )
{
  void (*fp)(int32_t) = &f;
}
