Introduction

The Get Next Line project is designed for students at the 42 School. It focuses on creating a function that reads from a file descriptor, handling dynamic buffers and static variables. This project reinforces skills in memory control and string manipulation, which are essential for efficient programming in C.

Features

• Dynamic Buffer Management: Efficiently handle memory allocation and deallocation.
• Static Variable Handling: Understand the use of static variables in C.
• String Manipulation: Work with strings to extract lines from a buffer.
• Efficient I/O Operations: Utilize the read() function for reading data.
• Low-Level Programming: Gain experience with file descriptors and system calls.

Installation

To get started with the Get Next Line project, follow these steps:

1. Clone the repository:

   git clone https://github.com/jhonnyMena/Get_Next_Line.git

2. Navigate to the project directory:

   cd Get_Next_Line

3. Compile the source files using gcc:

   gcc -o get_next_line get_next_line.c

4. Ensure you have the necessary permissions to execute the compiled file.

Usage

To use the get_next_line function, include the header file in your C program. Here’s a simple example:

#include "get_next_line.h"

int main() {
    int fd = open("example.txt", O_RDONLY);
    char *line;

    while ((line = get_next_line(fd)) != NULL) {
        printf("%s\n", line);
        free(line);
    }
    close(fd);
    return 0;
}

This example opens a file called example.txt, reads each line using get_next_line, and prints it to the console.

Functionality

The core function, get_next_line, operates as follows:

1. Read Data: It reads data from the file descriptor using the read() system call.
2. Buffer Management: It manages a dynamic buffer to store incoming data.
3. Line Extraction: It extracts a line from the buffer each time it is called.
4. Return Value: The function returns a pointer to the line read, or NULL if the end of the file is reached.

Memory Management

Proper memory management is crucial in C programming. The Get Next Line project emphasizes:

• Dynamic Memory Allocation: Using malloc to allocate memory for buffers.
• Memory Deallocation: Ensuring all allocated memory is freed to prevent leaks.
• Static Variables: Understanding how static variables retain their values between function calls.
