<p class=MsoNormal><font size=2 color=black face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:black'>Is there a technical reason that char
functions like putchar tend to promote the chars to ints? putchar and getchar
have 'always' had a return type of int. Some of this 'tradition' has to do with
a historical desire to make everything an integer so it will run fast on a
pdp11 I guess, but if I make a mistake and return a char instead of an int,
does something break? Does the wrong half of the int get used as the return
value if there is a size mismatch? I can see how you can return a char in an
int, but how do you return an int in a char? What gets returned? The hi byte or
the lo byte?</span></font></p>
