how to read a line of text using littlefs

#include "littlefs/lfs.h"

/*
Note that this code assumes that lfs is a pointer to a valid LittleFS instance, 
and file is a pointer to a valid LittleFS file that has been opened for reading.
The buf parameter is the buffer where the line will be stored, 
and size is the maximum size of the buffer.
*/

int read_line(lfs_t *lfs, lfs_file_t *file, char *buf, size_t size) {
    int i = 0;
    while (i < size) {
        int read = lfs_file_read(lfs, file, &buf[i], 1);
        if (read < 1) {
            break;
        }
        if (buf[i] == '\n') {
            i++;
