string::shrink_to_fit

Request the removal of unused capacity.

Synopsis

void
shrink_to_fit();

Description

This performs a non-binding request to reduce capacity() to size(). The request may or may not be fulfilled.

Complexity

At most, linear in size().

If reallocation occurs, all iterators including any past-the-end iterators, and all references to characters are invalidated. Otherwise, no iterators or references are invalidated.
