CS461 notes -- complete
create header function
seq num in socket
make sure not negative 1.
assign
/* a structure to contain an internet address
defined in the include file in.h */
struct sockaddr_in {
short sin_family; /* should be AF_INET */
u_short sin_port;
struct in_addr sin_addr;
char sin_zero[8]; /* not used, must be zero */
};
struct in_addr {
unsigned long s_addr;
};
ISSUES:
why aren't the retransmits working?
we aren't deallocating sockets properly
blocking close? is it necessary? better performance without it?
-make it a non-blocking close
Do the initialization bryan was talking about.
