Logger4C Library

Overview

This is a simple C library for logging messages to both the console and a log file. It provides functionality to customize log levels, log file rotation, and log message formatting.

Features

Customizable Log Levels: Define different log levels such as DEBUG, INFO, SUCCESS, WARNING, and ERROR.
Console and File Logging: Log messages can be output to both the console and a specified log file.
Log File Rotation: Automatically rotate log files when they exceed a specified maximum size.
Customizable Log Message Prefix: Add custom prefixes to log messages for better categorization.
ANSI Color Support: Different log levels can be displayed in different colors on the console for improved readability.

Getting Started

To use the logger library in your project, follow these steps:

Clone or download the repository.
Include the logger.h header file in your project.
Initialize the logger using the init_logger() function, specifying the desired log levels, log file path, and other settings.
Use the log_message() function to log messages at different log levels.
Optionally, customize log message prefixes or set a custom log file path using the provided helper functions.
Close the logger using the close_logger() function when done.

Usage Example

#include "logger.h"

int main() {
    struct Logger logger;
    init_logger(&logger, DEBUG, ERROR, "app.log", NULL, LOG_INTO_FILE);
    
    log_message(&logger, INFO, "Initializing application...");
    log_message(&logger, WARNING, "This is a warning message.");
    log_message(&logger, ERROR, "An error occurred!");

    close_logger(&logger);
    
    return 0;
}
