示例1: create_path
void bcp_implementation::create_path(const fs::path& p)
{
if(!fs::exists(m_dest_path / p))
{
// recurse then create the path:
create_path(p.branch_path());
fs::create_directory(m_dest_path / p);
}
}示例2: copy_path
void bcp_implementation::copy_path(const fs::path& p)
{
assert(!fs::is_directory(m_boost_path / p));
