where is class std::out_of_range fully defined?

Question

I am searching under /usr/include/c++ on my Ubuntu Linux. In /usr/include/c++/stdexcept, I found this:

class out_of_range : public logic_error
{
public:
    explicit out_of_range(const string& __arg);
 };

But I can't find anywhere the definition of out_of_range() constructors.

Also when the STL throws an out_of_range() exception, it uses (example taken from stl_vector.h):

__throw_out_of_range(__N("vector::_M_range_check"));

And, the only thing I can find for __throw_out_of_range() is:

void __throw_out_of_range(const char*) __attribute__((__noreturn__));

Can you kindly point me to where the definitions of the out_of_range class?

Answer 1

They're probably defined in libstdc++. You can get the source code on the GCC website. On Ubuntu distros, you just have the library installed (libstdc++.so), not the source code. The stuff you found are just the declarations, not the definitions.

Answer 2

std::out_of_range is fully defined in §19.2.5 Class out_of_range [out.of.range] of the C++11 standard.
