Sam Lantinga 316ff3847b Fixed bug 4526 - replace SDL_RW* macros with functions for using in bindings 
ace

I got this bug in SDL_ttf:
https://bugzilla.libsdl.org/show_bug.cgi?id=4524
Sylvain proposed solution:
SDL_RWseek(RWops, 0, RW_SEEK_SET);

And it works, but i can use it my project, because it written in C# with SDL2-CS wrapper and there not export for macroses:
#define SDL_RWsize(ctx)         (ctx)->size(ctx)
#define SDL_RWseek(ctx, offset, whence) (ctx)->seek(ctx, offset, whence)
#define SDL_RWtell(ctx)         (ctx)->seek(ctx, 0, RW_SEEK_CUR)
#define SDL_RWread(ctx, ptr, size, n)   (ctx)->read(ctx, ptr, size, n)
#define SDL_RWwrite(ctx, ptr, size, n)  (ctx)->write(ctx, ptr, size, n)
#define SDL_RWclose(ctx)        (ctx)->close(ctx)

Therefore, I suggest replacing this macros with functions so that they can be exported and used in bindings

Sam Lantinga f465f24d73 Fixed bug 3760 - RWops doesn't check for integer overflow when stdio_fseek only supports 32 bits 
Simon Hug

When RWops seeks with fseek or fseeko it uses the types long or off_t which can be 32 bits on some platforms. stdio_seek does not check if the 64-bit integer for the offset fits into a 32-bit integer. Offsets equal or larger than 2 GiB will have implementation-defined behavior and failure states would be very confusing to debug.

The attached patch adds range checking by using the macros from limits.h for long type and some bit shifting for off_t because POSIX couldn't be bothered to specify min and max macros.

It also defines HAVE_FSEEKI64 in SDL_config_windows.h so that the Windows function gets picked up automatically with the default config.

And there's an additional error message for when ftell fails.

Sam Lantinga a48c9e6df8 Fixed bug 3292 - SDL_rwops and 64-bit file I/O 
Juha Niemim?

On AmigaOS 4 platform with Newlib 'C' library, there is a problem with failing fseeko64. This seemed to be caused by using fopen instead of fopen64.

Sam Lantinga dc40018438 Added an API SDL_LoadFile_RW() to load all the data from an SDL data stream, and a convenience macro SDL_LoadFile() to load all the data from a file. 2017-08-09 11:58:38 -07:00

Philipp Wiesemann 0e45984fa0 Fixed crash if initialization of EGL failed but was tried again later. 
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().
