Not exactly.  If you're talking about the number zero then == 0 and != 0
are good style.  "if (size == 0) ".  Other times we're talking about
error codes or whatever and not the number zero so it should be
"if (ret) ".  Also for strcmp() functions, please use != 0 and == 0.

	if (strcmp(foo, bar) != 0)  <-- read this as "foo != bar"
	if (strcmp(foo, bar) == 0)  <-- read this as "foo == bar"
	if (strcmp(foo, bar) < 0)  <-- read this as "foo < bar"
