naginterfaces.library.omp.in_​parallel

naginterfaces.library.omp.in_parallel()

in_parallel returns $True$ if called from within an active OpenMP parallel region, and $False$ otherwise.

Returns

inparbool

$True$ if called from within an active OpenMP parallel region, and $False$ otherwise.

Notes

in_parallel, for multithreaded implementations, returns $True$ if called from within an active OpenMP parallel region, and $False$ otherwise.

In serial implementations of the NAG Library this function will always return $False$. See the X06 Introduction for a discussion of the behaviour of these functions when called in serial.
