nag_omp_get_nested (x06ahc), for multi-threaded implementations, tests whether the nesting of OpenMP parallel regions has been enabled as if with a call to nag_omp_set_nested (x06agc). The return value will be

1

if nesting is enabled or

0

if it is disabled.

In serial implementations of the NAG C Library nag_omp_get_nested (x06ahc) will always return

0

. See the x06 Chapter Introduction for a discussion of the behaviour of these functions when called in serial.
