How to compare two struct memories

void*(* _Eina_Value_Struct_Operations::copy)(const Eina_Value_Struct_Operations *ops, const Eina_Value_Struct_Desc *desc, const void *memory)

How to copy struct memory from an existing Eina_Value, if not provided alloc() will be used, then every member is copied using eina_value_type_copy() with member's type.

const Eina_Value_Struct_Member*(* _Eina_Value_Struct_Operations::find_member)(const Eina_Value_Struct_Operations *ops, const Eina_Value_Struct_Desc *desc, const char *name)

How to find description for member. For huge structures consider using binary search, stringshared, hash or gperf. The default function does linear search using strcmp().
