struct hostent *gethostbyname(const char *name)
Note that hostent.h_addr_list is a field with variant length.
How does the function gethostbyname have the implementation that returns a pointer pointing to a struct but doesn't require the caller to release the resource?
All examples used in the famous book Unix Network Programming Vol 1 by R. Stevens do not contain code to release those returned pointers and I assume that these are not ignorance. Also one example from MSDN does the same thing example of usage
