The Code Analyser LCLint

Debugging code is never fun, but this tool makes it a bit easier.
Annotations of LCLint

All LClint annotations have a common syntax, which is


All annotations are inserted within code in the same places we can insert comments; thus, its presence in the code does not affect normal compilation.

The most frequent location of the annotations is near the location of modifying semantics; e.g., in the definition of types, if the annotations are going to affect that type.

LCLint Annotations

LCLint has almost a hundred commands. Some of the most useful ones are shown in the sidebar “LCLint Annotations”. We are not activating or deactivating types of checks with these commands, but enriching the code so that LCLint has information on the semantics of the program and is able to do its analysis more accurately.

Naming Conventions

The use of naming conventions is a programming technique which has many users, but also many detractors. LCLint does not force you to use naming conventions, but it contains support for some of them. Supported naming conventions are Slovak, Czech and Czechoslovakian.

Slovak-Naming Convention

The rule of the Slovak-naming convention is that identifiers are constructed with the scheme abstracttypeVarname. The abstract type and the identifier name are separated with the first character of the identifier name in upper case. The annotations of LCLint related to the Slovak naming convention are shown in the sidebar. Remember that a type's name must never have a capital letter when using the Slovak-naming convention.

Czech-Naming Convention

The rule of the Czech-naming convention is that identifiers are constructed with the scheme abstracttype_varname. The abstract type name and the identificator name are separated by an underline character. The modifiers related to Czech-naming convention are shown in the sidebar. Remember that a type's name must never have an underline character when using the Czech-naming convention.

Czechoslovakian-Naming Convention

The Czechoslovakian-naming convention is the same as using Czech- and Slovak-naming convention at the same time. That is why there are valid Czech and Slovak indentificators in the Czechoslovakian-naming convention. The modifiers related to Czechoslovakian naming convention are shown in the sidebar. Remember that a type's name must never have an underline character or a capital letter when using the Czechoslovakian-naming convention.

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
