Functions

static int hostent2su (union sockaddr_union *su, struct hostent *he, unsigned int idx, unsigned short port)

inits a struct sockaddr_union from a struct hostent, an address index in the hostent structure and a port no. (host byte order) WARNING: no index overflow checks!

converts an ip_addr structure to a hostent

static int matchnet (struct ip_addr *ip, struct net *net)

returns 1 if ip & net.mask == net.ip ; 0 otherwise & -1 on error [ diff. address families ])
