CIB pdf toolbox 2 has a so called job-based interface. Normally you process a usecase by:

1. Creating a JOB-Handle
2. Setting for this JOB-Handle several properties to configure the JOB
3. Executing the job
4. Optionally getting some output properties to read results of the JOB
5. Deleting the JOB-Handle

Core functions are described below, which are exposed from the library.
For higher level, there are convenience wrapper functions whose description can be found in Test documentation section.

On Windows all interface functions are following the stdcall calling convention.
