### librdf_version_string

    extern const char * const librdf_version_string;

Redland librdf version as a string.

### librdf_copyright_string

    extern const char * const librdf_copyright_string;

Copyright string (multiple lines).

### librdf_short_copyright_string

    extern const char * const librdf_short_copyright_string;

### librdf_alloc_memory ()

    void *              librdf_alloc_memory                 (size_t size);

Allocate memory inside the library similar to `malloc()`.

Required for some runtimes where memory must be freed within the same shared object it was allocated in.

`size` : | alloc size
Returns : | pointer to memory or NULL on failure

### librdf_calloc_memory ()

    void *              librdf_calloc_memory                (size_t nmemb,
                                                             size_t size);

Allocate zeroed array of items inside the library similar to `calloc()`.

Required for some runtimes where memory must be freed within the same shared object it was allocated in.

`nmemb` : | number of members
`size` : | size of member
Returns : | pointer to memory or NULL on failure

### librdf_free_memory ()

    void                librdf_free_memory                  (void *ptr);

Free memory allocated in the library.

Required for some runtimes where memory must be freed within the same shared object it was allocated in.

`ptr` : | pointer to free

### REDLAND_DEPRECATED

    #define REDLAND_DEPRECATED __attribute__((deprecated))

When defined before a function, indicates that the function has been deprecated and may be replaced in a future release. With some versions of gcc this may give a compilation warning.
