// Capture all local variables inside the block by reference:
BOOST_SCOPE_EXIT(&) {
}

// Capture all local variables inside the block by value:
BOOST_SCOPE_EXIT(=) {
}

// Capture a and b by reference, c by value,
// all other local variables by reference
BOOST_SCOPE_EXIT(&, &a, &b, c) {
}

// Capture a and b by reference, c by value,
// all other local variables by value
BOOST_SCOPE_EXIT(=, &a, &b, c) {
}
