freeaddrinfo - release address information memory
#include <sys/socket.h> #include <netdb.h> void freeaddrinfo(struct addrinfo *ai);
The freeaddrinfo() function frees one or more addrinfo structures returned by getaddrinfo(3C), along with any additional storage associated with those structures. If the ai_next member of the structure is not null, the entire list of structures is freed. The freeaddrinfo () function supports the freeing of arbitrary sublists of an addrinfo list originally returned by getaddrinfo().
