Here is a link to its current documentation . Get Number of Threads
Syntax
number = thread_alloc::num_threads()

Purpose
Determine the number of threads as set during parallel_setup .

number
The return value number has prototype



    size_t number

and is equal to the value of num_threads in the previous call to parallel_setup . If there was no such previous call, the value one is returned.

Example
The example and test thread_alloc.cpp uses this routine.
