get_next_line

get_next_line is a function that reads and returns a single line from a file descriptor each time it's called, until the end of the file is reached.

Description

The get_next_line function reads text from the given file descriptor and returns it line by line. It uses a buffer to store the read content and processes it to provide a line every time the function is called. The function is designed to handle multiple file descriptors simultaneously and keep track of the progress for each file descriptor independently.

Usage

1. Clone this repository to your project directory:

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

2. Include the get_next_line.h header in your code.

3. Call the get_next_line function with the file descriptor you want to read from as an argument. The function will return a pointer to a string containing the next line read from the file.

4. Free the allocated memory when done with each line.

Compilation

Compile your program 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 -o your_program

Adjust BUFFER_SIZE as needed to set the buffer size for reading data.

Examples

Usage example:

#include "get_next_line.h"
#include <fcntl.h>
#include <stdio.h>

int main(void)
{
    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;
}
