SYNOPSIS

#include <xti_inet.h>

DESCRIPTION

The following symbol is defined to identify the ISO Transport protocol level:

Symbol	Protocol Level
T_INET_TP	TCP

The following symbols are defined with distinct integer values to identify TCP-level options:

Symbol	Option
T_TCP_NODELAY	do not delay packets to coalesce
T_TCP_MAXSEG	get maximum segment size
T_TCP_KEEPALIVE	check whether connections are alive

Structure type t_kpalive is defined with the following members for use with TCP_KEEPALIVE option:

Member	Type	Contents
kp_onoff	t_scalar_t	option on/off
kp_timeout	t_scalar_t	timeout in minutes

The following symbol is defined to identify the UDP protocol level:

Symbol	Protocol Level
T_INET_UDP	UDP

The following symbol is defined with integer value to identify the UDP-level checksum option:

Symbol	Option
T_UDP_CHECKSUM	checksum computation

The following symbol is defined to identify the IP protocol level:

Symbol	Protocol Level
T_INET_IP	IP

The following symbols are defined with distinct integer values to identify IP-level options:

Symbol	Option
T_IP_OPTIONS	IP per-packet options
T_IP_TOS	IP per-packet type of service
T_IP_TTL	IP per-packet time to live
T_IP_REUSEADDR	allow local address reuse
T_IP_DONTROUTE	just use interface addresses
T_IP_BROADCAST	permit sending of broadcast messages

The following symbols are defined with distinct integer values to identify IP Types of Service:

Symbol	Type of Service
T_NOTOS	normal
T_LDELAY	low delay
T_HITHRPT	high throughput
T_HIREL	high resilience
T_LOCOST	low cost

The following symbols are defined with distinct integer values to identify IP Type of Service precedence levels:

Symbol	IP TOS Precedence Level
T_ROUTINE	routine
T_PRIORITY	priority
T_IMMEDIATE	immediate
T_FLASH	flash
T_OVERRIDEFLASH	override flash
T_CRITIC_ECP	critical/ECP
T_INETCONTROL	internetwork control
T_NETCONTROL	network control

Macro SET_TOS(prec, tos) is defined such that SET_TOS(prec, tos) is the value of the IP Type of Service field for Type of Service tos and precedence prec.
