The C/C++ technique for passing parameters is always the same, regardless of calling convention: All parameters are passed by value, except for arrays, which are translated into the address of the first member. To pass data by reference, pass a pointer to it. ...
Just in case you needed to, you can wrap an array into a struct/class and pass it by value to a function:template<typename T, int N> struct array { T value[N]; T & operator[](int i) { return value[i]; } };template<typename T, int N> void passByValue(array<T, N> a) {...
typedef std::function<bool (int)> Filter; bool Foo(int i) { return i == 0; } void BarCaller(Filter bar) //pass by value { bar(2); } Filter bar = std::bind(&Foo, std::placeholders::_1); //now you can pass bar wherever you want BarCaller(bar); Share Improve this answer...

Function parameters are always passed by value. Pass-by-reference is simulated in C by explicitly passing pointer values. http://en.wikipedia.org/wiki/C_(programming_language) Jul 30, 2011 at 6:33am Disch(13742) The real question is why should they? They didn't implement classes or templa...
First argument is a C "int", passed by value ;;; c INTEGER(C_INT), VALUE,INTENT(IN) :: int_arg ;;; ! Second and third arguments are C "char *", represented ;;; ! in Fortran by an array of single characters of kind C_CHAR. ;;; ! Note that the language allows ...
By value When you pass an argument by value, you pass a copy of the value in memory. The function operates on the copy. This means that when a function changes the value of an argument passed by value, the effect is local to that function; the copy changes but the original value in...
