## Description

This project is part of the curriculum at Ecole 42. The goal of "42_get_next_line" is to create a function that reads a line from a file descriptor.

The `get_next_line` function reads a line from a file descriptor. A "line" is defined as a succession of characters that end with a newline ('\n') or EOF (End of File) from the input file.

The function allocates memory for the line read, which must be freed by the caller when it is no longer needed. It returns 1 if a line has been read, 0 if the reading is complete, and -1 in case of an error.

## Usage

1. Install.

```bash

git clone https://github.com/cypri1-dev/42_get_next_line.git

cd 42_get_next_line

```

2. To use the `get_next_line` function, include the header file `get_next_line.h` in your project. Then, call the function with the file descriptor from which you want to read a line.

## Example Usage

```c

#include "get_next_line.h"

int main(void)

{

    char *line;

    int fd;

    int ret;

    fd = open("example.txt", O_RDONLY);

    if (fd == -1)

        return (1);

    while ((ret = get_next_line(fd, &line)) > 0)

    {

        printf("%s\n", line);

        free(line);

    }

    if (ret == -1)

        return (1);

    close(fd);

    return (0);

}

```
