NAG CL Interface
a00acc (licence)
1
Purpose
a00acc 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 functions. In particular, the use of this function is highly recommended in programs that call NAG Library functions within multithreaded sections (e.g., OpenMP parallel regions). The function need only be called once, before the start of the first multithreaded section.
2
Specification
The function may be called by the names: a00acc, nag_info_licence or nag_licence_query.
3
Description
a00acc returns the logical value Nag_TRUE if a valid licence is found, otherwise Nag_FALSE is returned.
On non licence-managed implementations, Nag_TRUE is always returned.
