## Description

Static variables for version numbers and strings, copyright strings and home page. Functions for in-library memory allocation and deallocation.

## Functions

### 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.

#### Parameters

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.

#### Parameters

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.

#### Parameters

ptr | pointer to free |
