NAG Library Routine Document
a00acf (licence)
1
Purpose
a00acf provides a convenient means of checking the availability of a valid licence key on licence-managed implementations before starting computations that will use NAG Library routines. In particular, the use of this function is highly recommended in programs that call NAG Library routines within multithreaded sections (e.g., OpenMP parallel regions). The function need only be called once, before the start of the first multithreaded section.
