Alternatively, and especially in a library API, using bool is a clear specification of semantics. An int parameter could have many meanings. An int return value similarly. In both cases, using "bool" makes the usage instantly more clear, without the need for comments, or man pages, or Doxygen, or super_long_parameter_names, or whatever. I think it's useful.
