SDL_HINT_THREAD_STACK_SIZE

A string specifying SDL's threads stack size in bytes or "0" for the backend's default size

Header File

Defined in [SDL_hints.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_hints.h), but apps should _only_ `#include "SDL.h"`!

Syntax

#define SDL_HINT_THREAD_STACK_SIZE              "SDL_THREAD_STACK_SIZE"

Remarks

Use this hint in case you need to set SDL's threads stack size to other than the default. This is specially useful if you build SDL against a non glibc libc library (such as musl) which provides a relatively small default thread stack size (a few kilobytes versus the default 8MB glibc uses). Support for this hint is currently available only in the pthread, Windows, and PSP backend.

Instead of this hint, in 2.0.9 and later, you can use SDL_CreateThreadWithStackSize(). This hint only works with the classic SDL_CreateThread().

Default

By default the backend's default threads stack size is used.
