get_next_line() is a function designed to read a file descriptor line by line in the C programming language. This repository contains an implementation of the get_next_line() function, which can be used to read lines from a file or standard input.

The get_next_line function reads a line from a file descriptor and returns it as a string. It provides a convenient way to process large files line by line without having to load the entire file into memory at once.

To use the get_next_line function in your C program, you can follow these steps:

1. Clone the repository:

git clone https://github.com/zakelh6/get_next_line.git

2. Include the get_next_line.h header file in your program:

#include "get_next_line.h"

3. Compile your program along with the get_next_line function:

gcc -Wall -Wextra -Werror -D BUFFER_SIZE=32 your_program.c get_next_line.c get_next_line_utils.c

4. Start using the get_next_line function in your program:

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

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

    close(fd);
    return 0;
}

The function signature of get_next_line is as follows:

char *get_next_line(int fd);

• fd: The file descriptor from which to read the next line.

The get_next_line function returns a pointer to a string containing the next line read from the file descriptor. It returns NULL when the end of the file is reached or an error occurs.
