SDL_enabled_assert - The macro used when an assertion is enabled.

       This macro is available since SDL 3.2.0.

Simple Directmedia Layer                           SDL 3.2.20                              SDL_enabled_assert(3)

       This isn't for direct use by apps, but this is the code that is inserted when an SDL_assert is enabled.

       The do{}while(0) avoids dangling else problems:

              if (x) SDL_assert(y); else blah();

       ... without the do/while, the "else" could attach to this macro's "if". We try to handle just the minimum
       we  need  here  in a macro...the loop, the static vars, and break points. The heavy lifting is handled in
       SDL_ReportAssertion().

condition
              the condition to assert.
