Function Documentation

◆ SDL_GetWindowWMInfo()

SDL_bool SDL_GetWindowWMInfo ( SDL_Window window,
SDL_SysWMinfo info 
)

This function allows access to driver-dependent window information.

Parameters
windowThe window about which information is being requested
infoThis structure must be initialized with the SDL version, and is then filled in with information about the given window.
Returns
SDL_TRUE if the function is implemented and the version member of the info struct is valid, SDL_FALSE otherwise.

You typically use this function like this:

if ( SDL_GetWindowWMInfo(window, &info) ) { ... }
