/* * This external variable can be set by any debugger to flag to the runtime that we
25
are currently executing inside a debugger. This will allow the debugger to override
26
the number of threads spawned in a parallel region by using __kmp_omp_num_threads() (below).
27
* When __kmp_debugging is TRUE, each team and each task gets a unique integer identifier
28
that can be used by debugger to conveniently identify teams and tasks.
29
* The debugger has access to __kmp_omp_debug_struct_info which contains information
30
about the OpenMP library's important internal structures. This access will allow the debugger
31
to read detailed information from the typical OpenMP constructs (teams, threads, tasking, etc. )
32
during a debugging session and offer detailed and useful information which the user can probe
33
about the OpenMP portion of their code.
