c++ - How to distinguish between bind() in sys/sockets.h and std::bind? -


i'm using g++ 4.6.0 compile c++ code compiled in earlier versions.

if ( bind(icontrol, (struct sockaddr *) &sa, sizeof(sa)) == -1)   throw runtime_error ("bind");

where icontrol socket, , sa struct sockaddr_in.

however, in g++ 4.6 following error:

comms.cpp:93:66: error: no match ‘operator==’ in ‘std::bind(_functor&&, _argtypes&& ...) [with _functor = int&, _argtypes = {sockaddr*, long unsigned int}, typename std::_bind_helper<_functor, _argtypes>::type = std::_bind<int(sockaddr*, long unsigned int)>]((* &((sockaddr*)(& sa))), (* &16ul)) == -0x00000000000000001’

comms.cpp:93:66: note: candidates are:

followed page , half of possible candidates.

it appears mixing bind function in sys/sockets.h std::bind in functional . how disambiguate 2 without rewriting whole source file remove using namespace std?

qualify global: ::bind(...) (and make sure have right headers included).

edit: (i got idea @bo persson's comment) solid option change using namespace std; several using <thing> like:

using std::cout; using std::endl; using std::string; // etc.

this lets old code compile , doesn't bring std::bind global namespace.
