I had to do a mini project where I had to use write() in C the code works fine but when I use valgrind to check it I get two errors
First:The first error I get in valgrind
and second:The second error I get

here is the function where I used write()

int add_to_file(dir_data_t *elem,char *output,char *name){

    char path[1024];
    snprintf(path, sizeof(path), "%s/%s", output, name);

    int fd = open(path, O_WRONLY | O_CREAT | O_TRUNC, S_IRUSR | S_IWUSR);
    if (fd == -1) {
        printf("Error opening file (add_to_file)n");
        exit(EXIT_FAILURE);
    }

    ssize_t bytes_written; 
    bytes_written = write(fd, elem, sizeof(dir_data_t));
    if (bytes_written == -1) {
        perror("Error writing to the file (add_to_file)");
        close(fd);
        return 1;
    }

    close(fd);
    return 0;
}

As I said the code works and I get everything done as I need but I am curious why do I get this and how to solve this eventually to not appear anymore? I use the structure as static so I don’t alloc memory in my code that’s why I don’t really understand how I got that.
