Classes

class  bux::C_EntryLog
 Log on both declaration point and end of block scope with an unique id. More...

Namespaces

namespace  bux
 THE common namespace of bux library.
namespace  bux::user
 Function prototypes declared in this subnamespace are required to be implemented by user so that functions declared under namespace bux in the same header can be linked properly without errors.
