Description

x06xaf can be used to determine whether you are using a serial or multi-threaded implementation of the NAG Library. In particular, with this information the behaviour of the other routines in this chapter can be predicted, as described in the X06 Chapter Introduction.
The routine returns 1 when a multi-threaded implementation of the Library is being used and 0 if a serial implementation is being used.
