9859c05178 Added a default case to the switch statement in the HEADER FILE to prevent compiler warnings about missing defaults. This change helps avoid compilation breaks when warnings are treated as errors. 2025-09-16 17:16:50 -07:00

.wikiheader-options: Treat SDL int types (Uint64, etc) as API prefixes. 
This makes any reference to them in the docs link to their wiki pages.

Also fixup the integer type documentation, so the SDL2 wiki _has_ actual
pages for them.  :)

2660da6f5c Always allocate zt in output of SDL_iconv_string() 
Before this, the function could not be used on buffers,
as it would not account for the zero-termination unless
it was included in the input.

3bf7994fe2 Add and use SDL_FALLTHROUGH for fallthroughs 
Case fallthrough warnings can be suppressed using the __fallthrough__
compiler attribute. Unfortunately, not all compilers have this
attribute, or even have __has_attribute to check if they have the
__fallthrough__ attribute. [[fallthrough]] is also available in C++17
and the next C2x, but not everyone uses C++17 or C2x.

So define the SDL_FALLTHROUGH macro to deal with those problems - if we
are using C++17 or C2x, it expands to [[fallthrough]]; else if the
compiler has __has_attribute and has the __fallthrough__ attribute, then
it expands to __attribute__((__fallthrough__)); else it expands to an
empty statement, with a /* fallthrough */ comment (it's a do {} while
(0) statement, because users of this macro need to use a semicolon,
because [[fallthrough]] and __attribute__((__fallthrough__)) require a
semicolon).

Clang before Clang 10 and GCC before GCC 7 have problems with using
__attribute__ as a sole statement and warn about a "declaration not
declaring anything", so fall back to using the /* fallthrough */ comment
if we are using those older compiler versions.

Applications using SDL are also free to use this macro (because it is
defined in begin_code.h).

All existing /* fallthrough */ comments have been replaced with this
macro. Some of them were unnecessary because they were the last case in
a switch; using SDL_FALLTHROUGH in those cases would result in a compile
error on compilers that support __fallthrough__, for having a
__attribute__((__fallthrough__)) statement that didn't immediately
precede a case label.
