Reminder to everyone: the issue is: '13.4.2 says, "Functions that return a value must be assigned or used in an expression. Calling a nonvoid function as if it has no return value can result in a warning message." The first sentence implies that it is not possible to use a nonvoid function like a void function. The second implies that it is possible, just may give a warning.' I would like to point out some additional sources: 13.2: "A nonvoid function shall return a single value". A statement can not be a value. 13.4.1: "Function calls are expressions unless of type void, which are statements." An expression is not a statement. 13.5: "A nonvoid function call is an operand within an expression." I think all these make clear that it was not intended to allow a nonvoid function call as a statement. Especially the first sentence quoted from 13.4.2, which uses the word "must". The void cast exists exactly to allow users to do that. Otherwise, what is the point?
