This Fail-safe API library is designed to minimize crashes in C/C++ applications when generating log messages. The primary advantage of utilizing this library over other logging tools lies in its comprehensive runtime validation capabilities. It effectively mitigates common issues associated with the misuse of the printf() style logging, such as passing NULL, zero, or negative values for string types (%s), which are frequent causes of segmentation faults and runtime errors.

Key Features:

• Runtime Validation: The API performs extensive checks to identify potential execution flaws before they lead to application failure.
• Error Handling: In cases where a validation fails, the API seamlessly generates an error code and allows the application to continue processing without manual intervention.
• Bound Parameter Methodology: This library employs 18 different Bound Parameter verification techniques to ensure log messages are used accurately, fail-safe and reliable to generate.

Core API Functionality:

1. Utilizes a C-program print() style interface, familiar to programmers for logging messages.
2. Converts log message strings and their arguments into structured element/value pairs.
3. Analyzes these pairs to verify the accuracy of log message argument utilization.
4. Checks for unintentional misuse of log arguments by programmers.
5. Identifies potentially malicious patterns that may exploit printf() vulnerabilities.
6. Generates log messages suitable for both development and production environments.
7. Ensures robust and reliable operations through fail-safe mechanisms.

Usage Examples:

For a quick setup and usage of Wandi-SSAL API functions in C/C++ applications, refer to the following:

• LoggerStartUp()
• LoggerAppsMsg()
• LoggerShutDown()
  Setup and define your logger messages with the LoggerMessageDefines.txt configuration file.

Example Implementations:
