(This is the documentation for SDL3, which is the current stable version. SDL2 was the previous version!)

SDL_GetHint

Get the value of a hint.

Header File

Syntax

const char* SDL_GetHint(const char *name);

Function Parameters

const char *

name

the hint to query.

Return Value

(const char *) Returns the string value of a hint or NULL if the hint isn't set.

Thread Safety

It is safe to call this function from any thread, however the return value only remains valid until the hint is changed; if another thread might do so, the app should supply locks and/or make a copy of the string. Note that using a hint callback instead is always thread-safe, as SDL holds a lock on the thread subsystem during the callback.

Version

This function is available since SDL 3.1.3.
