Value:

    do\
    {\
        ::std::ostringstream lassUtilExceptionImplBuffer;\
        lassUtilExceptionImplBuffer << s_message;\
        throw t_exception(lassUtilExceptionImplBuffer.str(), LASS_PRETTY_FUNCTION);\

To throw an exception like util::Exception that accepts a message and a location string, you can supply those strings yourself, ore you can use this macro for your convenience.

This macro will fill in the location by itself so that you only have to worry about the message.
And as an extra, the message is streamed, so you can use the regular operator<< to concatenate variables in the message.

int foo = -5;
if (foo < 0)
{
    LASS_THROW_EX(util::Exception, "foo '" << foo << "' is less than zero");
}
