Write() [2/2]

void ns3::Buffer::Iterator::Write	(	Iterator	start,

Parameters

start	the start of the data to copy
end	the end of the data to copy

Write the data delimited by start and end in internal buffer and advance the iterator position by the number of bytes copied. The input iterators must not point to the same Buffer as we do to avoid overlapping copies. This is enforced in debug builds by asserts.
