Function Documentation

SCHInfoAddHostOSInfo()

int SCHInfoAddHostOSInfo	(	const char *	host_os,
		const char *	host_os_ip_range,
		int	is_ipv4
	)

Used to add the host-os-info data obtained from the conf.

Parameters

host_os	The host_os name/flavour from the conf file
host_os_ip_range	Pointer to a char string holding the ip/ip_netblock for the host_os specified in the first argument
is_ipv4	Indicates if the ip address to be considered for the default configuration is IPV4; if not it is IPV6. Specified using SC_HINFO_IS_IPV6 or SC_HINFO_IS_IPV4

Return values

0	On successfully adding the host os info to the Radix tree
-1	On failure \initonly (only specified from config, at the startup)
