As long as there is a simple way to throw an exception such that:
1. It is derived from std::exception
2. It contains information about the stack trace
It is ok for me.
This is the basic way to use Boost.Exception with Stacktrace:
#include
#include
#include <stdexcept>
#include <iostream>
typedef boost::error_info stacktrace_info;
template<class E> void throw_with_stacktrace( E const & e )
{
throw boost::enable_error_info( e ) << stacktrace_info(
boost::stacktrace::stacktrace() );
}
void f()
{
throw_with_stacktrace( std::runtime_error( "pumpkin" ) );
}
void g()
{
f();
}
int main()
{
try
{
g();
}
catch( boost::exception const & x )
{
std::cerr << boost::diagnostic_information( x ) << std::endl;
}
}
It's also possible to build upon BOOST_THROW_EXCEPTION instead:
#include
#include
#include <stdexcept>
#include <iostream>
typedef boost::error_info stacktrace_info;
#define BOOST_THROW_WITH_STACKTRACE( e ) try { BOOST_THROW_EXCEPTION( e ); }
catch( boost::exception & x ) { x << stacktrace_info(
boost::stacktrace::stacktrace() ); throw; }
void f()
{
BOOST_THROW_WITH_STACKTRACE( std::runtime_error( "pumpkin" ) );
}
void g()
{
f();
}
int main()
{
try
{
g();
}
catch( boost::exception const & x )
{
std::cerr << boost::diagnostic_information( x ) << std::endl;
}
}
