Detailed Description

For all functions, the argument s is a string that is displayed.

  it_assert(t,s);   // Abort if \c t is not true.
  it_assert0(t,s);  // Abort if \c t is not true and ASSERT_LEVEL = 2
  it_assert1(t,s);  // Abort if \c t is not true and ASSERT_LEVEL = 2 or 1
  it_error_if(t,s); // Abort if \c t is true.
  it_error(s);      // Abort.
  it_warning(s);    // Show a warning.

it_assert(), it_error() and it_warning() is always active while it_assert0() and it_assert1() depends on the ASSERT_LEVEL variable. If ASSERT_LEVEL == 0 then none of these are executed while if it is 1 only it_assert1() is executed.
