1 Scope of the Chapter

The functions in this chapter provide information about the NAG C Library.

nag_implementation_details (a00aac) enables you to determine the precise Mark and maintenance level of the NAG C Library which is being used, and also details of the implementation.

nag_licence_query (a00acc) enables you to check if a valid key is available for the library licence management system.

nag_implementation_separated_details (a00adc) is similar to nag_implementation_details (a00aac) but returns different aspects of an implementation, such as the product code and Mark in separate strings and integers.

Information about the precise implementation of the NAG C Library in use will be needed when communicating with the NAG Response Centre (see the Essential Introduction).
