Basic system services

This section describes the basic system services, which are provided for applications by the Circle base library libcircle.a. Only those classes are discussed here, which are directly used by applications. All Circle classes are listed in doc/classes.txt.

The Circle project does not provide a single centralized C++ header file. Instead the header file(s), which must be included for a specific class, function or macro definition are specified in the related subsection.
