The type FN_attrvalue_t is used to represent the contents of a single attribute value, within an attribute of type FN_attribute_t.
The representation of this structure is defined by XFN as follows:
typedef struct { size_t length; void *contents; } FN_attrvalue_t;
FN_attribute_t(3XFN), fn_attr_get_values(3XFN), xfn(3XFN)
