Hi,
from the manual
listen(2): listen for connections on socket - Linux man page
It has a parameter called backlog and it limits the maximum length of queue of pending list.
If I set backlog to 128, is it means no more than 128 packets can be handled by server?
If I have three... (3 Replies)

inet_network
INET(3) Linux Programmer's Manual INET(3)NAME
inet_aton, inet_addr, inet_network, inet_ntoa, inet_makeaddr, inet_lnaof, inet_netof - Internet address manipulation routines
SYNOPSIS
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
int inet_aton(const char *cp, struct in_addr *inp);
in_addr_t inet_addr(const char *cp);
in_addr_t inet_network(const char *cp);
char *inet_ntoa(struct in_addr in);
struct in_addr inet_makeaddr(int net, int host);
in_addr_t inet_lnaof(struct in_addr in);
in_addr_t inet_netof(struct in_addr in);
DESCRIPTION
inet_aton() converts the Internet host address cp from the standard numbers-and-dots notation into binary data and stores it in the struc-
ture that inp points to. inet_aton returns nonzero if the address is valid, zero if not.
The inet_addr() function converts the Internet host address cp from numbers-and-dots notation into binary data in network byte order. If
the input is invalid, INADDR_NONE (usually -1) is returned. This is an obsolete interface to inet_aton, described immediately above; it is
obsolete because -1 is a valid address (255.255.255.255), and inet_aton provides a cleaner way to indicate error return.
The inet_network() function extracts the network number in host byte order from the address cp in numbers-and-dots notation. If the input
is invalid, -1 is returned.
The inet_ntoa() function converts the Internet host address in given in network byte order to a string in standard numbers-and-dots nota-
tion. The string is returned in a statically allocated buffer, which subsequent calls will overwrite.
The inet_makeaddr() function makes an Internet host address in network byte order by combining the network number net with the local
address host in network net, both in local host byte order.
The inet_lnaof() function returns the local host address part of the Internet address in. The local host address is returned in local host
byte order.
The inet_netof() function returns the network number part of the Internet Address in. The network number is returned in local host byte
order.
The structure in_addr as used in inet_ntoa(), inet_makeaddr(), inet_lnoaf() and inet_netof() is defined in netinet/in.h as:
struct in_addr {
unsigned long int s_addr;
}
Note that on the i80x86 the host byte order is Least Significant Byte first, whereas the network byte order, as used on the Internet, is
Most Significant Byte first.
