clang 3.4 (trunk 194324) produces a pretty clear error message:
initializer_list:54:23: error: 'iterator' declared as a pointer to a reference of type
'std::basic_ofstream<char> &'
typedef const _E* iterator;
So no, it is not possible. See also Error: forming pointer to reference type 'const std::pair&'… I can't understand this error.
(gcc 4.7.2 and 4.8.1 crashes on this code due to some internal compiler error. I have submitted a bugreport.)
What you could do instead is to pass a pointer instead of a reference, something like this:
#include <fstream>
#include <initializer_list>
using namespace std;
void writeSomething(initializer_list<ofstream*> args) {
for (auto f : args )
*f << "hello" << endl;
}
int main() {
ofstream outputFile("data_1.txt");
ofstream outputFile2("data_2.txt");
writeSomething({&outputFile, &outputFile2});
}
However, I would much rather use a std::vector
instead. Using an initializer list for this purpose is very strange and confusing for me.
