Network Data Structures
// in ipV4
struct hostent {
    char* h_name;
    char** h_aliases;
    int h_addrtype;
    int h_length;
    char** h_addr_list;
};
struct in_addr {

};
Network Functions
struct hostent* getHostByName(const char* name);
struct hostent* getHostByAddr(const char* addr, int type, int length);
Abstractions with increasing modularity
  • function call – no modularity with caller/callee stack discipline
  • system call – enforced modularity – caller can’t access to the ghost of the stack space for system calls
  • pipe
  • network
