Define SDL_PLATFORM_* macros instead of underscored ones (#8875) 2024-01-24 01:40:51 +00:00
Sam Lantinga e2f35a16c2 Added <string.h> for declaration of memset() and memcpy() 2024-01-21 06:55:29 -08:00
Sam Lantinga 7a069cc4b0 Allow optimizing memcpy and memset where possible 
Modern C runtimes have well optimized memset and memcpy, so use those instead of dispatching into SDL's versions. In addition, some compilers can analyze memset and memcpy calls and directly turn them into optimized assembly.

Sam Lantinga 2faae8457d The C standard defines a boolean expression as a signed integer value. 
Microsoft came to the same conclusion:

Sam Lantinga 7681695875 Revert "Fixed signed/unsigned warnings with Visual Studio when comparing SDL_bool with boolean expressions" 
This reverts commit 61db102da9.

This causes the build to fail:
SDL_waylandwindow.c:1876:45: error: implicit truncation from 'int' to a one-bit wide bit-field changes value from 1 to -1 [-Werror,-Wsingle-bit-bitfield-constant-conversion]
            wind->fullscreen_was_positioned = SDL_TRUE;

Anonymous Maarten d6291d4d42 alloca: use alloca from <stdlib.h> on NetBSD 
The only generally portable way to do this is to use -std=gnu99,
"#include <stdlib.h>", and write "alloca".
__builtin_alloca does not seem to be available on NetBSD

docs: Remove Doxygen `\brief` tags. 
Doxygen and the wiki bridge don't need them; they'll both just use the first
line/sentence instead.

Fixes #8446.

Eddy Jansson 5f5abb6805 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.

Sam Lantinga e9b86eebf3 Functions which return function pointers now return SDL_FunctionPointer instead of void* 
This fixes the clang warning "Cast between pointer-to-function and pointer-to-object is an extension"

You can define SDL_FUNCTION_POINTER_IS_VOID_POINTER in your project to restore the previous behavior.

Sam Lantinga 7f23d71b6a Added SDL_modf() and SDL_modff() 
This function is useful for accumulating relative mouse motion if you want to only handle whole pixel movement.
e.g.
static float dx_frac, dy_frac;
float dx, dy;

/* Accumulate new motion with previous sub-pixel motion */
dx = event.motion.xrel + dx_frac;
dy = event.motion.yrel + dy_frac;

/* Split the integral and fractional motion, dx and dy will contain whole pixel deltas */
dx_frac = SDL_modff(dx, &dx);
dy_frac = SDL_modff(dy, &dy);
if (dx != 0.0f || dy != 0.0f) {
    ...
}

Sam Lantinga 0a48abc860 Switch header convention from `#include "SDL.h"` to `#include <SDL3/SDLh>` 
I ran this script in the include directory:
```sh
sed -i '' -e 's,#include "\(SDL.*\)",#include <SDL3/\1>,' *.h
```

I ran this script in the src directory:
```sh
for i in ../include/SDL3/SDL*.h
do hdr=$(basename $i)
   if [ x"$(echo $hdr | egrep 'SDL_main|SDL_name|SDL_test|SDL_syswm|SDL_opengl|SDL_egl|SDL_vulkan')" != x ]; then
        find . -type f -exec sed -i '' -e 's,#include "\('$hdr'\)",#include <SDL3/\1>,' {} \;
    else
        find . -type f -exec sed -i '' -e '/#include "'$hdr'"/d' {} \;
    fi
