SDL_LockProperties

Lock a group of properties.

Header File

Defined in <SDL3/SDL_properties.h>

Syntax

bool SDL_LockProperties(SDL_PropertiesID props);

Function Parameters

SDL_PropertiesID props the properties to lock.

Return Value

(bool) Returns true on success or false on failure; call SDL_GetError() for more information.

Remarks

Obtain a multi-threaded lock for these properties. Other threads will wait while trying to lock these properties until they are unlocked. Properties must be unlocked before they are destroyed.

The lock is automatically taken when setting individual properties, this function is only needed when you want to set several properties atomically or want to guarantee that properties being queried aren't freed in another thread.

Thread Safety

It is safe to call this function from any thread.

Version

This function is available since SDL 3.1.3.
