Detailed Description

LSA Header.

Common header for all LSAs. Never store or pass a pointer, just deal with it inline.

Member Function Documentation

size_t Lsa_header::copy_out

(

uint8_t *

to_uint8

)

const

Copy a wire format representation to the pointer provided.

A LSA header is a fixed length, the caller should have allocated enough space by calling the length() method.

Returns:

the number of bytes written.

Lsa_header Lsa_header::decode

(

uint8_t *

ptr

)

const throw (InvalidPacket)

Decode a LSA header and return a LSA header inline not a pointer.

A LSA header is a fixed length, the caller should have allocated enough space by calling the length() method.

static size_t Lsa_header::length

(

)

[inline, static]

Returns:

the length of an LSA header.
