NAME¶

SDL_GetPointerProperty - Get a pointer property from a group of properties.

HEADER FILE¶

Defined in SDL3/SDL_properties.h

SYNOPSIS¶

#include "SDL3/SDL.h"

void * SDL_GetPointerProperty(SDL_PropertiesID props, const char *name, void *default_value);

DESCRIPTION¶

By convention, the names of properties that SDL exposes on objects will start with "SDL.", and properties that SDL uses internally will start with "SDL.internal.". These should be considered read-only and should not be modified by applications.

FUNCTION PARAMETERS¶

props

the properties to query.

name

the name of the property to query.

default_value

the default value of the property.

RETURN VALUE¶

Returns the value of the property, or default_value if it is not set or not a pointer property.

THREAD SAFETY¶

It is safe to call this function from any thread, although the data returned is not protected and could potentially be freed if you call

SDL_SetPointerProperty () or

SDL_ClearProperty () on these properties from another thread. If you need to avoid this, use

SDL_LockProperties () and

SDL_UnlockProperties ().

AVAILABILITY¶

This function is available since SDL 3.1.3.
