Sam Lantinga 12f14bdb 2022-06-18T07:02:38 Fixed digit count in sscanf, e.g. "%1x"
Anonymous Maarten ae7446a9 2022-06-15T20:48:54 stlib: Extract SDL_memcpy and SDL_memset to its own file respectively This is done such that we can disable LTO for these 2 functions when building with MSVC. This is due to a limitation of Link Time Code Generation (LTCG). Code generation might generate a new reference to memset after linking has started. The LTCG must make assumptions about where memset is defined which is normally the C runtime.
Guldoman 74bcc5a0 2022-05-05T02:23:05 stdlib: Add `SDL_utf8strnlen`
Pierre Wendling 501a4991 2022-05-05T18:44:32 Add clang-format on/off comments where necessary. Comments were added in places where INDENT-ON/OFF comments are. Places like stdlib's asm don't need it as clang-format doesn't try to indent it.
Cameron Cawley 0cca71a8 2022-05-18T22:12:05 Use SDLCALL for callbacks in public APIs
Ozkan Sezer ec1a0f62 2022-05-17T01:33:02 SDL_malloc.c: workaround calling convention issues for real_xxx procs.
Frank Richter 0e63b514 2022-05-07T14:52:35 Don't define memcpy(), memset() when using static VC runtime. The linker will complain about duplicated symbols otherwise (see #3662, #5156).
Sam Lantinga 8cd908e0 2022-05-06T10:51:55 Fixed building with Visual Studio 2013 Added SDL_vacopy.h since it needs to be included after Windows headers

Ryan C. Gordon 8df045cc 2022-03-22T15:53:40 stdlib: just cast iconv()'s 2nd arg to void *. This makes the compiler happy (enough) regardless of whether the C runtime headers think this argument should be const or not. Fixes #4966.

Misa 3bf7994f 2021-09-27T14:38:12 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.
Sam Lantinga abc12a83 2021-11-11T15:58:44 Revert "Add and use `SDL_FALLTHROUGH` for fallthroughs" This reverts commit 66a08aa3914a98667f212e79b4f0b9453203d656. This causes problems with older compilers: https://github.com/libsdl-org/SDL/pull/4791#issuecomment-966630997

Sam Lantinga a91ab883 2021-08-06T12:28:03 Fixed building on Windows with cmake, ninja, and clang
Jessica Clarke 8f38ba4d 2021-07-29T18:02:47 Fix casts that should be using uintptr_t This is needed to support CHERI, and thus Arm's experimental Morello prototype, where pointers are implemented using unforgeable capabilities that include bounds and permissions metadata to provide fine-grained spatial and referential memory safety, as well as revocation by sweeping memory to provide heap temporal memory safety. On most systems (anything with a flat memory hierarchy rather than using segment-based addressing), size_t and uintptr_t are the same type. However, on CHERI, size_t is just an integer offset, whereas uintptr_t is still a capability as described above. Casting a pointer to size_t will strip the metadata and validity tag, and casting from size_t to a pointer will result in a null-derived capability whose validity tag is not set, and thus cannot be dereferenced without faulting. The audio and cursor casts were harmless as they intend to stuff an integer into a pointer, but using uintptr_t is the idiomatic way to do that and silences our compiler warnings (which our build tool makes fatal by default as they often indicate real problems). The iconv and egl casts were true positives as SDL_iconv_t and iconv_t are pointer types, as is NativeDisplayType on most OSes, so this would have trapped at run time when using the round-tripped pointers. The gles2 casts were also harmless; the OpenGL API defines this argument to be a pointer type (and uses the argument name "pointer"), but it in fact represents an integer offset, so like audio and cursor the additional idiomatic cast is needed to silence the warning.

Misa 3da58b47 2021-02-13T15:11:40 Fix errors with fallback impls of SDL_isxdigit() and SDL_ispunct() SDL_isxdigit() should only accept A-Fa-f, not A-Za-z (it shouldn't use SDL_isalpha()). SDL_ispunct() shouldn't accept spaces (it should use SDL_isgraph() instead).
Misa dfe219ec 2021-02-13T11:21:19 Add all missing "is characteristic" stdlib functions SDL has been missing a bunch of these 'isX' functions for some time, where X is some characteristic of a given character. This commit adds the rest of them to the SDL stdlib, so now we have: - SDL_isalpha() - SDL_isalnum() - SDL_isblank() - SDL_iscntrl() - SDL_isxdigit() - SDL_ispunct() - SDL_isprint() - SDL_isgraph()

Ozkan Sezer 8a32ee24 2020-12-30T01:00:24 removed MSVC strtok_s use from SDL_strtokr(). no other ??_s are used elsewhere in SDL_stdinc. besides, C11 has a strtok_s with a different signature.
Sam Lantinga 93ccdee8 2020-12-23T13:47:49 Fixed bug 5404 - stdlib: Added SDL_round, SDL_roundf, SDL_lround and SDL_lroundf Cameron Cawley stdlib: Added SDL_round, SDL_roundf, SDL_lround and SDL_lroundf The default implementation is based on the one used in the Windows RT video driver.
Sam Lantinga cb361896 2020-12-09T07:16:22 Fixed bug 5235 - All internal sources should include SDL_assert.h Ryan C. Gordon We should really stick this in SDL_internal.h or something so it's always available.

Ryan C. Gordon e410b34f 2020-07-24T22:24:03 stdlib: Corrected implementation of SDL_wcsncmp. It was a copy/paste of SDL_strcmp, apparently, not SDL_strncmp, so it ignored the maxlen parameter. Thanks to Jack Powell for pointing this out!

Sam Lantinga 342f62ca 2020-03-10T16:29:28 Fixed bug 5022 - SDL_iconv_string can get stuck in an infinite loop when encountering invalid characters ciremo6483 In `SDL_iconv_string` the `while (inbytesleft > 0)` loop can end up in a state where it never terminates because the library `iconv` function called from `SDL_iconv` doesn't consume any bytes. This happened when a `WCHAR_T` input string was being converted to `UTF-8` but contained invalid characters. It would first It would first skip a few bytes due to `case SDL_ICONV_EILSEQ` but when there were 3 bytes remaining of `inbytesleft` `iconv` just didn't consume anything more (but didn't throw an error either). It just so happens that the Microsoft Classic IntelliMouse `product_string` contains such invalid characters (`"Microsoft? Classic IntelliMouse?"`), meaning the function would get stuck with said mouse plugged in. A fix for this would be to check if `inbytesleft` was unchanged after an iteration and in that case either decrement the counter like when `SDL_ICONV_EILSEQ` is returned or simply break the loop.
Sam Lantinga aa384ad0 2020-03-02T15:21:07 Fixed bug 5001 - Feature request: SDL_isupper & SDL_islower

Ozkan Sezer d3fa42b8 2018-11-18T19:28:20 os/2 bits for SDL_malloc.c -- from libffi
Sam Lantinga 9e8e0fb7 2018-09-28T20:48:18 Fixed bug 4283 - SDL's version of memset is different from libc's janisozaur memset's documentation reads: * The memset() function shall copy c (converted to an unsigned char) into each of the first n bytes of the object pointed to by s. (http://pubs.opengroup.org/onlinepubs/9699919799/functions/memset.html) * Sets the first count characters of dest to the character c. (https://msdn.microsoft.com/en-us/library/1fdeehz6.aspx) * write a byte to a byte string (https://developer.apple.com/library/archive/documentation/System/Conceptual/ManPages_iPhoneOS/man3/memset.3.html) The highlight here is they all mean a single _byte_, even though memset receives a parameter of type int, which can hold more data than a single byte. SDL's implementation of memset, however, does not clear any of the higher bits, causing an erroneous behaviour when passed an argument bigger than 0xff.
Ozkan Sezer 31596f23 2018-09-29T01:24:10 SDL_vsnprintf: implemented '+' flag for signed integers printing. it is, of course, ignored for %u, %x, %o and %p.
Ozkan Sezer 49803c86 2018-09-29T00:51:24 SDL_vsnprintf: fix numerics if both zero-padding and a field are given. it used to place zeroes between the sign and the number. (space-padding from within SDL_PrintString() seems OK: spaces are added before sign.) also fixed the maxlen handling if the number has a sign.
Ozkan Sezer bb5516ac 2018-09-27T09:37:36 SDL_vsnprintf() updates for zero-padding: - remove force-enabling of pad_zeroes for %u for compatibility (was added in https://hg.libsdl.org/SDL/rev/701f4a25df89) - ignore pad_zeroes for %s and %S - ignore pad_zeroes for %d, %i and %u if a precision is given

Ozkan Sezer 652d59fb 2018-05-10T09:02:39 make sure SDL_vsnprintf() nul terminates if it is using _vsnprintf The change makes sure that SDL_vsnprintf() nul terminates if it is using _vsnprintf() for the job. I made this patch for Watcom, whose _vsnprintf() doesn't guarantee nul termination. The preprocessor check can be extended to windows in general too, if required. Closes bug #3769.
