enumerateDirectory method

bool enumerateDirectory(String path, Pointer<NativeFunction<SdlEnumerateDirectoryCallback>> callback, Pointer<Void> userdata)

Enumerate a directory in a storage container through a callback function.

This function provides every directory entry through an app-provided callback, called once for each directory entry, until all results have been provided or the callback returns either SDL_ENUM_SUCCESS or SDL_ENUM_FAILURE.

This will return false if there was a system problem in general, or if a callback returns SDL_ENUM_FAILURE. A successful return means a callback returned SDL_ENUM_SUCCESS to halt enumeration, or all directory entries were enumerated.

If path is NULL, this is treated as a request to enumerate the root of the storage container's tree. An empty string also works for this.

\param storage a storage container. \param path the path of the directory to enumerate, or NULL for the root. \param callback a function that is called for each entry in the directory. \param userdata a pointer that is passed to callback. \returns true on success or false on failure; call SDL_GetError() for more information.

\since This function is available since SDL 3.2.0.
