Detailed Description

Thread index table to provide portable natural thread indices.

A thread table provides a simple way to offer thread indices (starting from 0).

When a thread registers itself in the registry, its id is added to the vector of identifiers. When a thread deregisters itself from the registry its entry is modified to contain the empty thread id.

To get an integer index, users may call current_index, which provides the order number of the calling thread in the registry.

Note

This class is thread safe by means of using a spin-lock.
