Union of Standard Sets

Syntax
result = set_union(leftright)

Purpose
This is a simplified (and restricted) interface to the std::union operation.

Element
This is the type of the elements of the sets.

left
This argument has prototype
     const std::set<
Element>& left

right
This argument has prototype
     const std::set<
Element>& right

result
The return value has prototype
     std::set<
Element>& result
It contains the union of left and right . Note that C++11 detects that the return value is a temporary and uses it for the result instead of making a separate copy.

Example
The file set_union.cpp contains an example and test of this operation. It returns true if the test passes and false otherwise.
