void	a00adc (char impl, char prec, char pcode, char mkmaj, char mkmin, char hdware, char opsys, char ccomp, char fcomp, char vend, Nag_Boolean *licval)

The function may be called by the names: a00adc, nag_info_impl_details_separate or nag_implementation_separated_details.

3 Description

The NAG Library is available for use on a number of different computer systems. For each distinct system an implementation of the Library is prepared and this implementation is given a unique code. The specifics that define the implementation are: the working precision, the major and minor marks of the NAG Library, the target hardware and operating system, the compiler used, and the vendor library (if any) that is also required to be linked. a00adc may be called to return, in separate arguments, these specific details of the NAG Library implementation that is being used; it also returns whether a valid licence has been found for this implementation. This differs from a00aac which simply outputs the collected information in a readable form directly to the stdout (standard output) stream.

5 Arguments

1: $impl$ – char * Output

On exit: the implementation title which usually lists the target platform, operating system and compiler.

2: $prec$ – char * Output

On exit: the working or basic precision of the implementation. Some functions may perform operations in reduced precision or additional precision, but the great majority will perform all operations in basic precision.

3: $pcode$ – char * Output

On exit: the product code for the NAG Library implementation that is being used. The code has a discernible structure, but it is not necessary to know the details of this structure. The product code can be used to differentiate between individual product licence codes.

4: $mkmaj$ – char * Output

On exit: the major mark of the NAG Library implementation that is being used.

5: $mkmin$ – char * Output

On exit: the minor mark of the NAG Library implementation that is being used.

6: $hdware$ – char * Output

On exit: the target hardware for the NAG Library implementation that is being used.

7: $opsys$ – char * Output

On exit: the target operating system for the NAG Library implementation that is being used.

8: $ccomp$ – char * Output

On exit: the C compiler used to build the NAG Library implementation that is being used.

9: $fcomp$ – char * Output

On exit: the Fortran compiler used to build the NAG Library implementation that is being used.

10: $vend$ – char * Output

On exit: the subsidiary library, if any, that must be linked with the NAG Library implementation that is being used. If the implementation does not require a subsidiary library then the string

'(self-contained)'

will be returned in vend.

11: $licval$ – Nag_Boolean * Output

On exit: specifies whether or not a valid licence has been found for the NAG Library implementation that is being used.

6 Error Indicators and Warnings

None.

7 Accuracy

8 Parallelism and Performance

9 Further Comments

10 Example

This example makes a call of a00adc, collects information on the NAG Library implementation that is being used and prints it out in a form that is similar to the output obtained by a call to a00aac.
