Available on crate feature dep_sdl3 only.
Expand description

Get metadata about your app.

This returns metadata previously set using SDL_SetAppMetadata() or SDL_SetAppMetadataProperty(). See SDL_SetAppMetadataProperty() for the list of available properties and their meanings.

§Parameters

  • name: the name of the metadata property to get.

§Return value

Returns the current value of the metadata property, or the default if it is not set, NULL for properties with no default.

§Thread safety

It is safe to call this function from any thread, although the string returned is not protected and could potentially be freed if you call SDL_SetAppMetadataProperty() to set that property from another thread.

§Availability

This function is available since SDL 3.2.0.
