Typedefs
typedef struct Store	Store
	Reference to a Nix store.

Functions
nix_err	nix_libstore_init (nix_c_context *context)
	Initializes the Nix store library.
nix_err	nix_libstore_init_no_load_config (nix_c_context *context)
	Like nix_libstore_init, but does not load the Nix configuration.
Store *	nix_store_open (nix_c_context *context, const char *uri, const char ***params)
	Open a nix store.
void	nix_store_free (Store *store)
	Deallocate a nix store and free any resources if not also held by other Store instances.
nix_err	nix_store_get_uri (nix_c_context *context, Store *store, nix_get_string_callback callback, void *user_data)
	get the URI of a nix store
nix_err	nix_store_get_storedir (nix_c_context *context, Store *store, nix_get_string_callback callback, void *user_data)
	get the storeDir of a Nix store, typically "/nix/store"
StorePath *	nix_store_parse_path (nix_c_context *context, Store *store, const char *path)
	Parse a Nix store path that includes the store dir into a StorePath.
bool	nix_store_is_valid_path (nix_c_context *context, Store *store, const StorePath *path)
	Check if a StorePath is valid (i.e. that corresponding store object and its closure of references exists in the store).
nix_err	nix_store_real_path (nix_c_context *context, Store *store, StorePath *path, nix_get_string_callback callback, void *user_data)
	Get the physical location of a store path.
nix_err	nix_store_realise (nix_c_context *context, Store *store, StorePath *path, void *userdata, void(*callback)(void *userdata, const char *outname, const StorePath *out))
	Realise a Nix store path.
nix_err	nix_store_get_version (nix_c_context *context, Store *store, nix_get_string_callback callback, void *user_data)
	get the version of a nix store.
nix_derivation *	nix_derivation_from_json (nix_c_context *context, Store *store, const char *json)
	Create a nix_derivation from a JSON representation of that derivation.
StorePath *	nix_add_derivation (nix_c_context *context, Store *store, nix_derivation *derivation)
	Add the given nix_derivation to the given store.
nix_err	nix_store_copy_closure (nix_c_context *context, Store *srcStore, Store *dstStore, StorePath *path)
	Copy the closure of path from srcStore to dstStore.
nix_err	nix_store_get_fs_closure (nix_c_context *context, Store *store, const StorePath *store_path, bool flip_direction, bool include_outputs, bool include_derivers, void *userdata, void(*callback)(nix_c_context *context, void *userdata, const StorePath *store_path))
	Gets the closure of a specific store path.
nix_derivation *	nix_store_drv_from_store_path (nix_c_context *context, Store *store, const StorePath *path)
	Returns the derivation associated with the store path.
StorePath *	nix_store_query_path_from_hash_part (nix_c_context *context, Store *store, const char *hash)
	Query the full store path given the hash part of a valid store path, or empty if no matching path is found.
nix_err	nix_store_copy_path (nix_c_context *context, Store *srcStore, Store *dstStore, const StorePath *path, bool repair, bool checkSigs)
	Copy a path from one store to another.
