| 3.1 | Why must value-result arguments such as the length of a socket address structure be passed by reference? |
| 3.2 | Why do both the readn and writen functions copy the void* pointer into a char* pointer? |
| Figure A.10). Write a new function named inet_pton_loose that handles these scenarios: If the address family is AF_INET and inet_pton returns 0, call inet_aton and see if it succeeds. Similarly, if the address family is AF_INET6 and inet_pton returns 0, call inet_aton and if it succeeds, return the IPv4-mapped IPv6 address. |
