that we are currently executing inside a debugger. This will allow the

debugger to override the number of threads spawned in a parallel region by
25
using __kmp_omp_num_threads() (below).
26
* When __kmp_debugging is TRUE, each team and each task gets a unique integer

identifier that can be used by debugger to conveniently identify teams and

tasks.

* The debugger has access to __kmp_omp_debug_struct_info which contains
30
information about the OpenMP library's important internal structures. This
31
access will allow the debugger to read detailed information from the typical
32
OpenMP constructs (teams, threads, tasking, etc. ) during a debugging
33
session and offer detailed and useful information which the user can probe
34
about the OpenMP portion of their code. */
