       These functions allow an application to manipulate the fields of a security context string
       without requiring it to know the format of the string.

       context_new() returns a new context initialized to a context string.

       context_str() returns a pointer to the string value of the context_t, valid until the next
       call to context_str() or context_free() for the same context_t*.

       context_free() frees the storage used by a context.

       context_type_get(),  context_range_get(),  context_role_get(),  context_user_get()  get  a
       pointer to the string value of a context component.

       Note: Values returned by the get functions are only valid until the next  call  to  a  set
       function or context_free() for the same context_t structure.

       context_type_set(),  context_range_set(),  context_role_set(),  context_user_set()  set  a
       context component.


       On failure context_*_set() functions return non-zero and 0 on success.

       The other functions return NULL on failure and non-NULL on success.

       On failure errno is set appropriately.
