Trying to compile the following code on a FreeBSD 5.4 machine, using GCC
4.0.1....
# 1 "Test.cpp"
# 0 "<built-in>"
# 1 "<command line>"
# 1 "Test.cpp"
class OutStream
{
public:
OutStream();
};
inline OutStream & operator<<( OutStream & output, const int & value )
{
return output;
}
class Client
{
public:
OutStream send()
{
return OutStream();
}
};
int main(int argc,char **argv)
{
Client myclient;
int x = 32;
int y = 64;
myclient.send() << x << y;
return 0;
}
Produces the following output...
