and will be withdrawn at Mark 31.3. Replaced by x06akc
() will return
. If x06ahc
() will return the number of nested active parallel regions allowed.
, for multithreaded implementations, tests whether the nesting of OpenMP parallel regions has been enabled as if with a call to x06agc
. The return value will be
if nesting is enabled or
if it is disabled.
In serial implementations of the NAG Library x06ahc
will always return
. See the X06 Chapter Introduction
for a discussion of the behaviour of these functions when called in serial.
Background information to multithreading can be found in the Multithreading
for a demonstration of how to use x06ahc
