boost::logic::indeterminate — Keyword and test function for the indeterminate tribool value.
bool indeterminate(tribool x, unspecified dummy = unspecified);
indeterminate function has a dual role. It's first role is as a unary function that tells whether the tribool value is in the "indeterminate" state. It's second role is as a keyword representing the indeterminate (just like "true" and "false" represent the true and false states). If you do not like the name "indeterminate", and would prefer to use a different name, see the macro
