plucky (3) SDL_GetHint.3.gz

NAME

       SDL_GetHint - Get the value of a hint.

HEADER FILE

       Defined in SDL3/SDL_hints.h

SYNOPSIS

       #include "SDL3/SDL.h"

       const char * SDL_GetHint(const char *name);

FUNCTION PARAMETERS

       name   the hint to query.

RETURN VALUE

       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.

AVAILABILITY

       This function is available since SDL 3.2.0.
