◆ DetectAddressCmpIPv6()

int DetectAddressCmpIPv6	(	DetectAddress *	a,

Compares 2 addresses(address ranges) and returns the relationship between the 2 addresses.

Parameters

a	Pointer to the first address instance to be compared.
b	Pointer to the second address instance to be compared.

Return values

ADDRESS_EQ	If the 2 address ranges a and b, are equal.
ADDRESS_ES	b encapsulates a. b_ip1[...a_ip1...a_ip2...]b_ip2.
ADDRESS_EB	a encapsulates b. a_ip1[...b_ip1....b_ip2...]a_ip2.
ADDRESS_LE	a_ip1(...b_ip1==a_ip2...)b_ip2
ADDRESS_LT	a_ip1(...b_ip1...a_ip2...)b_ip2
ADDRESS_GE	b_ip1(...a_ip1==b_ip2...)a_ip2
ADDRESS_GT	a_ip1 > b_ip2, i.e. the address range for 'a' starts only after the end of the address range for 'b'

◆ DetectAddressCutNotIPv6()

int DetectAddressCutNotIPv6	(	DetectAddress *	a,
		DetectAddress **	b
	)

Cuts and returns an address range, which is the complement of the address range that is supplied as the argument.

For example:

If a = ::-2000::, then a = 2000::1-FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF and b = NULL If a = 2000::1-FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF, then a = ::-2000:: and b = NULL If a = 2000::1-20FF::2, then a = ::-2000:: and b = 20FF::3-FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF

Parameters

a	Pointer to an address range (DetectAddress) instance whose complement has to be returned in a and b.
b	Pointer to DetectAddress pointer, that will be supplied back with a new DetectAddress instance, if the complement demands so.
