Re: [Boost-users] doubt on boost::bind and boost::function

P.S. I also tried this one below with unnamed namespace boost::function< bool(const std::string& ) > fooPtr ( boost::bind( &TestBoosFeb18::IsMemberFunction, this, ::_1 ) ); but I have the error error: invalid use of non-static member function On Fri, Feb 19, 2010 at 4:09 PM, Conoscenza Silente < abruzzoforteegentile@gmail.com> wrote:

If I use _1 it seems that there is a conflict with the placehodler of boost::lambda so I switched to using boost::arg<1> to avoid the conflict but I still have an error saying.

TestBoost_Feb18.h:34: error: expected primary-expression before ‘)’ token

If I want to use the placeholders of boos::bind explicitly ( since I am using explicitly boost::bind ) is boost::arg<n> good?

Below is my code #include

boost::function< bool(const std::string& ) > fooPtr ( boost::bind( &CA::IsMemberFunction, this, boost::arg<1> ) );

Do you know what I am doing wrong? Is the signature fine? Thanks

try boost::bind( &CA::IsMemberFunction, this, _1 )

Cheers,
