SDL_Vulkan_GetInstanceExtensions

Get the names of the Vulkan instance extensions needed to create a surface with SDL_Vulkan_CreateSurface.

Header File

Syntax

SDL_bool SDL_Vulkan_GetInstanceExtensions(SDL_Window *window,
                                          unsigned int *pCount,
                                          const char **pNames);

Function Parameters

SDL_Window *	window	A window for which the required Vulkan instance extensions should be retrieved (will be deprecated in a future release).
unsigned int *	pCount	A pointer to an unsigned int corresponding to the number of extensions to be returned.
const char **	pNames	NULL or a pointer to an array to be filled with required Vulkan instance extensions.

Return Value

(SDL_bool) Returns SDL_TRUE on success, SDL_FALSE on error.

Remarks

If pNames is NULL, then the number of required Vulkan instance extensions is returned in pCount. Otherwise, pCount must point to a variable set to the number of elements in the pNames array, and on return the variable is overwritten with the number of names actually written to pNames. If pCount is less than the number of required extensions, at most pCount structures will be written. If pCount is smaller than the number of required extensions, SDL_FALSE will be returned instead of SDL_TRUE, to indicate that not all the required extensions were returned.

The window parameter is currently needed to be valid as of SDL 2.0.8, however, this parameter will likely be removed in future releases

Version

This function is available since SDL 2.0.6.
