Detailed Description

LcConfig PACKAGE - error handling in cclcconfig …

The error signals the end of an operation with an undesirable result or state.

• The error is defined using the both enum: enum liblcconfig::LcErrorE and enum liblcconfig::LcErrorTypeE
• In a programming language WITHOUT explicit error handling (eg "C") this value is returned and the subsequent code must process the error, eg with LcErrorE_Check.
• In a programming language WITH explicit error handling (eg "Java"), the error is converted into an exception and the program flow is aborted with an error message.
