These functions historically didn't set the error indicator on overflow.
Before commit 447b508a "error: SDL's allocators now call SDL_OutOfMemory
on error", their callers would call SDL_OutOfMemory() instead, which was
assumed to be close enough in meaning: "that's a silly amount of memory
that would overflow size_t" is similar to "that's more memory than
is available". Now that responsibility for calling SDL_OutOfMemory()
has been pushed down into SDL_calloc() and friends, the functions that
check for overflows might as well set more specific errors.

Simple DirectMedia Layer (SDL) Version 3.0
Simple DirectMedia Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware via OpenGL and Direct3D. It is used by video playback software, emulators, and popular games including Valve's award winning catalog and many Humble Bundle games.
More extensive documentation is available in the docs directory, starting with README.md. If you are migrating to SDL 3.0 from SDL 2.0, the changes are extensively documented in README-migration.md.
Enjoy!
