+ * # CategoryStorage
+ *
+ * The storage API is a high-level API designed to abstract away the
+ * portability issues that come up when using something lower-level (in SDL's
+ * case, this sits on top of the [Filesystem](CategoryFilesystem) and
+ * [IOStream](CategoryIOStream) subsystems). It is significantly more
+ * restrictive than a typical filesystem API, for a number of reasons:
+ *
+ * 1. **What to Access:** A common pitfall with existing filesystem APIs is
+ * the assumption that all storage is monolithic. However, many other
+ * platforms (game consoles in particular) are more strict about what _type_
+ * of filesystem is being accessed; for example, game content and user data
+ * are usually two separate storage devices with entirely different
+ * characteristics (and possibly different low-level APIs altogether!).
+ *
+ * 2. **How to Access:** Another common mistake is applications assuming that
+ * all storage is universally writeable - again, many platforms treat game
+ * content and user data as two separate storage devices, and only user data
+ * is writeable while game content is read-only.
+ *
+ * 3. **When to Access:** The most common portability issue with filesystem
+ * access is _timing_ - you cannot always assume that the storage device is
+ * always accessible all of the time, nor can you assume that there are no
+ * limits to how long you have access to a particular device.
+ *
+ * Consider the following example:
+ *
+ * ```c
+ * void ReadGameData(void)
+ * {
+ *     extern char** fileNames;
+ *     extern size_t numFiles;
+ *     for (size_t i = 0; i < numFiles; i += 1) {
+ *         FILE *data = fopen(fileNames[i], "rwb");
+ *         if (data == NULL) {
+ *             // Something bad happened!
+ *         } else {
+ *             // A bunch of stuff happens here
+ *             fclose(data);
+ *         }
+ *     }
+ * }
+ *
+ * void ReadSave(void)
+ * {
+ *     FILE *save = fopen("saves/save0.sav", "rb");
+ *     if (save == NULL) {
+ *         // Something bad happened!
+ *     } else {
+ *         // A bunch of stuff happens here
+ *         fclose(save);
+ *     }
+ * }
+ *
+ * void WriteSave(void)
+ * {
+ *     FILE *save = fopen("saves/save0.sav", "wb");
+ *     if (save == NULL) {
+ *         // Something bad happened!
+ *     } else {
+ *         // A bunch of stuff happens here
+ *         fclose(save);
+ *     }
+ * }
+ * ```
+ *
+ * Going over the bullet points again:
+ *
+ * 1. **What to Access:** This code accesses a global filesystem; game data
+ * and saves are all presumed to be in the current working directory (which
+ * may or may not be the game's installation folder!).
+ *
+ * 2. **How to Access:** This code assumes that content paths are writeable,
+ * and that save data is also writeable despite being in the same location as
+ * the game data.
+ *
+ * 3. **When to Access:** This code assumes that they can be called at any
+ * time, since the filesystem is always accessible and has no limits on how
+ * long the filesystem is being accessed.
+ *
+ * Due to these assumptions, the filesystem code is not portable and will fail
+ * under these common scenarios:
+ *
+ * - The game is installed on a device that is read-only, both content loading
+ *   and game saves will fail or crash outright
+ * - Game/User storage is not implicitly mounted, so no files will be found
+ *   for either scenario when a platform requires explicitly mounting
+ *   filesystems
+ * - Save data may not be safe since the I/O is not being flushed or
+ *   validated, so an error occurring elsewhere in the program may result in
+ *   missing/corrupted save data
+ *
+ * When using SDL_Storage, these types of problems are virtually impossible to
+ * trip over:
+ *
+ * ```c
+ * void ReadGameData(void)
+ * {
+ *     extern char** fileNames;
+ *     extern size_t numFiles;
+ *
+ *     SDL_Storage *title = SDL_OpenTitleStorage(NULL, 0);
+ *     if (title == NULL) {
+ *         // Something bad happened!
+ *     }
+ *     while (!SDL_StorageReady(title)) {
+ *         SDL_Delay(1);
+ *     }
+ *
+ *     for (size_t i = 0; i < numFiles; i += 1) {
+ *         void* dst;
+ *         Uint64 dstLen = 0;
+ *
+ *         if (SDL_GetStorageFileSize(title, fileNames[i], &dstLen) && dstLen > 0) {
+ *             dst = SDL_malloc(dstLen);
+ *             if (SDL_ReadStorageFile(title, fileNames[i], dst, dstLen)) {
+ *                 // A bunch of stuff happens here
+ *             } else {
+ *                 // Something bad happened!
+ *             }
+ *             SDL_free(dst);
+ *         } else {
+ *             // Something bad happened!
+ *         }
+ *     }
+ *
+ *     SDL_CloseStorage(title);
+ * }
+ *
+ * void ReadSave(void)
+ * {
+ *     SDL_Storage *user = SDL_OpenUserStorage("libsdl", "Storage Example", 0);
+ *     if (user == NULL) {
+ *         // Something bad happened!
+ *     }
+ *     while (!SDL_StorageReady(user)) {
+ *         SDL_Delay(1);
+ *     }
+ *
+ *     Uint64 saveLen = 0;
+ *     if (SDL_GetStorageFileSize(user, "save0.sav", &saveLen) && saveLen > 0) {
+ *         void* dst = SDL_malloc(saveLen);
+ *         if (SDL_ReadStorageFile(user, "save0.sav", dst, saveLen)) {
+ *             // A bunch of stuff happens here
+ *         } else {
+ *             // Something bad happened!
+ *         }
+ *         SDL_free(dst);
+ *     } else {
+ *         // Something bad happened!
+ *     }
+ *
+ *     SDL_CloseStorage(user);
+ * }
+ *
+ * void WriteSave(void)
+ * {
+ *     SDL_Storage *user = SDL_OpenUserStorage("libsdl", "Storage Example", 0);
+ *     if (user == NULL) {
+ *         // Something bad happened!
+ *     }
+ *     while (!SDL_StorageReady(user)) {
+ *         SDL_Delay(1);
+ *     }
+ *
+ *     extern void *saveData; // A bunch of stuff happened here...
+ *     extern Uint64 saveLen;
+ *     if (!SDL_WriteStorageFile(user, "save0.sav", saveData, saveLen)) {
+ *         // Something bad happened!
+ *     }
+ *
+ *     SDL_CloseStorage(user);
+ * }
+ * ```
+ *
+ * Note the improvements that SDL_Storage makes:
+ *
+ * 1. **What to Access:** This code explicitly reads from a title or user
+ * storage device based on the context of the function.
+ *
+ * 2. **How to Access:** This code explicitly uses either a read or write
+ * function based on the context of the function.
+ *
+ * 3. **When to Access:** This code explicitly opens the device when it needs
+ * to, and closes it when it is finished working with the filesystem.
+ *
+ * The result is an application that is significantly more robust against the
+ * increasing demands of platforms and their filesystems!
+ *
+ * A publicly available example of an SDL_Storage backend is the
+ * [Steam Cloud](https://partner.steamgames.com/doc/features/cloud)
+ * backend - you can initialize Steamworks when starting the program, and then
+ * SDL will recognize that Steamworks is initialized and automatically use
+ * ISteamRemoteStorage when the application opens user storage. More
+ * importantly, when you _open_ storage it knows to begin a "batch" of
+ * filesystem operations, and when you _close_ storage it knows to end and
+ * flush the batch. This is used by Steam to support
+ * [Dynamic Cloud Sync](https://steamcommunity.com/groups/steamworks/announcements/detail/3142949576401813670)
+ * ; users can save data on one PC, put the device to sleep, and then continue
+ * playing on another PC (and vice versa) with the save data fully
+ * synchronized across all devices, allowing for a seamless experience without
+ * having to do full restarts of the program.
+ *
+ * ## Notes on valid paths
+ *
+ * All paths in the Storage API use Unix-style path separators ('/'). Using a
+ * different path separator will not work, even if the underlying platform
+ * would otherwise accept it. This is to keep code using the Storage API
+ * portable between platforms and Storage implementations and simplify app
+ * code.
+ *
+ * Paths with relative directories ("." and "..") are forbidden by the Storage
+ * API.
+ *
+ * All valid UTF-8 strings (discounting the NULL terminator character and the
+ * '/' path separator) are usable for filenames, however, an underlying
+ * Storage implementation may not support particularly strange sequences and
+ * refuse to create files with those names, etc.

+ * may contain wildcard characters `*` (match everything) and `?` (match one
+ * character). If pattern is NULL, no filtering is done and all results are
+ * returned. Subdirectories are permitted, and are specified with a path

+ *
+ * `flags` may be set to SDL_GLOB_CASEINSENSITIVE to make the pattern matching
+ * case-insensitive.
+ *
+ * The returned array is always NULL-terminated, for your iterating
+ * convenience, but if `count` is non-NULL, on return it will contain the
+ * number of items in the array, not counting the NULL terminator.
+ *
+ * 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 pattern the pattern that files in the directory must match. Can be
+ *                NULL.
+ * \param flags `SDL_GLOB_*` bitflags that affect this search.
+ * \param count on return, will be set to the number of items in the returned
+ *              array. Can be NULL.
+ * \returns an array of strings on success or NULL on failure; call
+ *          SDL_GetError() for more information. The caller should pass the
+ *          returned pointer to SDL_free when done with it. This is a single
+ *          allocation that should be freed with SDL_free() when it is no
+ *          longer needed.

+ * \threadsafety It is safe to call this function from any thread, assuming
