get_next_line

Description

The aim of this project is to make you code a function that returns a line ending with a newline, read from a file descriptor.

Usage

int		main(int argc, char **argv)
{
	int		fd;
	char	*line;
	int		ret;

	fd = open(argv[1], O_RDONLY);
	if (fd == -1)
	{
		printf("failed to open file \n");
		return (0);
	}
	ret = 1;
	while (ret > 0 && argc)
	{
		ret = get_next_line(fd, &line);
		printf(" %d | %s\n", ret, line);
		free(line);
	}
	return (0);
}

• return 1 if it filled line
• return 0 when it reaches the end of file
• return -1 if it encountered any error while reading the file
