#define C_STR

X

)

Value:

static_cast<std::ostringstream&>(std::ostringstream().flush() << X).str().c_str()

Convert a stream of things to a const char *.

Suppose you have a function:

void func(const char * c);

Then you can write:

func(C_STR("foo"<<1<<"bar"));

which is equivalent to:

func("foo1bar");
