How do I switch between the two types of runtime APIs?

In order to switch between the two types of the runtime APIs provided, you have to ASN.1-compile your ASN.1 syntax with the proper corresponding command-line option and then link your application with the proper OSS library file.

To use the space-optimized runtime, you should compile your ASN.1 syntax with the -controlFile option specified.

To use the time-optimized runtime, you should compile your ASN.1 syntax with the -codeFile option specified.

Whichever runtime you are using you will need to link your application as described in the answer to: I'm just starting out on Windows. Which library file should I link my application with to use the OSS API functions?

The samples included with some of the Knowledge Center answers are meant for your general understanding of the OSS products. Different versions of the products might produce slightly different outputs. Consult the products documentation and samples for the most up-to-date products information and code examples.
