if
x06ahf() returned
,
x06akf() will return
. If
x06ahf() returned
,
x06akf() will return the number of nested active parallel regions allowed.
x06ahf, for multithreaded implementations, tests whether the nesting of OpenMP parallel regions has been enabled as if with a call to
x06agf. The return value will be
if nesting is enabled or
if it is disabled.
Note the equivalent OpenMP routine omp_get_nested() returns a logical value.
In serial implementations of the NAG Library
x06ahf will always return
. See the
X06 Chapter Introduction for a discussion of the behaviour of these routines when called in serial.
