Function Documentation

gf_net_has_ipv6()

u32 gf_net_has_ipv6

(

)

gets ipv6 support

Returns IPV6 support information.

Returns

2 if the machine has IPV6 support, 1 if the library was compiled with IPV6 support, 0 otherwise

Here is the caller graph for this function:

gf_net_is_ipv6()

Bool gf_net_is_ipv6

(

const char *

address

)

checks address type

Checks if an address is an IPV6 or IPV4 one.

Parameters

address

address to check

Returns

true 1 if address is IPV6 one, 0 otherwise

Here is the caller graph for this function:

gf_net_enum_interfaces()

Bool gf_net_enum_interfaces	(	gf_net_ifce_enum	do_enum,
		void *	enum_cbk
	)

enumerate network interfaces

Enumerates available network interfaces with IP. The callback function is called for each defined IP address of the interface

Parameters

enum_cbk	user data passed to callback function, may be NULL
do_enum	callback function

Returns

true if enumeration succeeded, false if not supported
