Document Summary
C++ technology in c close(fd) closes a file close(5) when 5 is not opened returns -1 and set errno, but microsoft throws exception. Can define own function called rpl_close that takes into account of two kinds of error handling int rpl_close(int fl) { Catch n = 1; errno = ebadf; return n; define close rpl_close. Uses the macro language of c to build a new language that takes into account of all linux systems handling of error exceptions and of all microsoft"s way of handling error exceptions. No function calls but has predicates connected by logic. Clarity mathematician have hundreds of years of notational experiences. Parallelity escape from the non newman between bottleneck. Functional form: higher order function that takes function as arguments f g h or h(x) = f(g(x)) Determined by calls and recursion i. e to order evaluation 1, 2, 3, 4, 5, must write a recursive function.
