if  (also while, until, for, etc...)  treats anything other than 0 (or NULL
which is usually defined as 0 or
(void*)0) as true.

so things like -1 (and even strings) are treated as true

assuming function(parm) returns 2 ....

if(function(parm) == TRUE) puts("2 is not 1: this won't happen");

if(function(parm)) puts("2 is not false: this will happen");

if("pigs fly") puts("All non-null pointers are true");
