Member Functions Documentation

CurHopLimit()

TInt

CurHopLimit

(

)

const [inline]

Gets Cur Hop Limit.

Flags()

TInt

Flags

(

)

const [inline]

Gets flags byte

H()

TInt

(

)

const [inline]

Gets Home Agent Configuration (H) flag

HeaderLength()

TInt

HeaderLength

(

)

const [inline]

Gets the header length.

Note:

This length is not the true length of the ICMP header. This only covers the fixed part.

M()

TInt

(

)

const [inline]

Gets Managed Address Configuration (M) flag

MaxHeaderLength()

TInt

MaxHeaderLength

(

)

[static, inline]

Gets the maximum header length.

Note:

This length is not the true length of the ICMP header. This only covers the fixed part.

MinHeaderLength()

TInt

MinHeaderLength

(

)

[static, inline]

Gets the minimum header length.

O()

TInt

(

)

const [inline]

Gets Other Address Configuartion (O) flag

Prf()

TInt

Prf

(

)

const [inline]

Gets default route preference.

Experimental: draft-draves-ipngwg-router-selection-01.txt Default Router Preferences and More-Specific Routes

ReachableTime()

TUint32

ReachableTime

(

)

const [inline]

Gets the value of reachable timer.

RetransTimer()

TUint32

RetransTimer

(

)

const [inline]

Gets the value of retransmit timer.

RouterLifetime()

TInt

RouterLifetime

(

)

const [inline]

Gets the lifetime of the defaul route.

If non-zero, specifies how long (in seconds) this router is willing to act as a default router.

Note:

This is badly named. The parameter controls only the default route processing. The value ZERO does not mean that the sender is not a router.

SetCurHopLimit(TInt)

void

SetCurHopLimit

(

void

SetRetransTimer

(

TUint32

aTimer

)

[inline]

Sets the value of the retransmit timer

Parameters

TUint32 aTimer

The timer value

SetRouterLifetime(TInt)

void

SetRouterLifetime

(
