The get_next_line project is an essential tool for C programmers. It provides a function for reading one line at a time from a file descriptor, offering a deep dive into file I/O in the C programming language.

• Efficiently reads text from files or streams, one line at a time.
• Supports multiple file descriptors simultaneously.
• Handles memory allocation dynamically.
• Ensures modular and maintainable code.

To use get_next_line, follow these steps:

1. Include the get_next_line function in your C project.
2. Call the function with a file descriptor to read lines from it.

#include "get_next_line.h"

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

    while (get_next_line(fd, &line) > 0) {
        printf("%s\n", line);
        free(line);
    }

    close(fd);
    return 0;
}

To compile with default settings, use the following command:

$ clang -Wall -Werror -Wextra *.c -D BUFFER_SIZE=8

You can modify BUFFER_SIZE as needed.

For extra features, compile with this command:

$ clang -Wall -Werror -Wextra *.c -D BUFFER_SIZE=8 -D INTER_LINE=5

You can customize both BUFFER_SIZE and INTER_LINE.

Depending on your operating system, you may need to adjust the definition of OPEN_MAX. To find the limit of open files your operating system can support, use the following command:

$ ulimit -n
