boost::algorithm::erase_tail_copy — Erase tail algorithm.
template<typename OutputIteratorT, typename CollectionT> OutputIteratorT erase_tail_copy(OutputIteratorT Output, const CollectionT & Input, unsigned int N); template<typename SequenceT> SequenceT erase_tail_copy(const SequenceT & Input, unsigned int N);
Remove the tail from the input. The tail is a suffix of a seqence of given size. If the sequence is shorter then required, the whole string is considered to be the tail. The result is a modified copy of the input. It is returned as a sequence or copied to the output iterator.
Parameters
An input string
Length of the head
An output iterator to which the result will be copied
Returns:
An output iterator pointing just after the last inserted character or a modified copy of the input
Notes:
The second variant of this function provides the strong exception-safety guarantee
