<strong>Software</strong> <strong>Architecture</strong>: <strong>Foundations</strong>, <strong>Theory</strong>, <strong>and</strong> <strong>Practice</strong><br />
Framework #1: stdio<br />
St<strong>and</strong>ard I/O framework used in C programming language<br />
Each process is a filter<br />
Reads input from st<strong>and</strong>ard input (aka ‘stdin’)<br />
Writes output to st<strong>and</strong>ard output (aka ‘stdout’)<br />
Also a third, unbuffered output stream called st<strong>and</strong>ard error<br />
(‘stderr’) not considered here<br />
Low <strong>and</strong> high level operations<br />
getchar(…), putchar(…) move one character at a time<br />
printf(…) <strong>and</strong> scanf(…) move <strong>and</strong> format entire strings<br />
Different implementations may vary in details (buffering<br />
strategy, etc.)<br />
