Heres a little class I made for handling binary flags. Its templated so it can hold an interger type of any size up to 64 bit. typedef unsigned char Uint8; typedef unsigned short Uint16; typedef unsigned int Uint32; typedef unsigned long long Uint64; template <class IntType> class Flag { public: Flag(){flags=0;} ~Flag(){}; bool FlipBit(Uint8 bit); bool SetBit(Uint8 bit); bool ResetBit(Uint8 bit); bool GetBit(Uint8 bit); IntType GetFlags(); void PrintFlags(); private: IntType flags; }; template <class IntType> bool Flag<IntType>::FlipBit(Uint8 bit) { if(bit >= sizeof(IntType)CHAR_BIT) return false; flags ^= (1 << bit); return true; } template <class IntType> bool Flag<IntType>::SetBit(Uint8 bit) { if(bit >= sizeof(IntType)CHAR_BIT) return false; flags \|= (1 << bit); return true; } template <class IntType> bool Flag<IntType>::ResetBit(Uint8 bit) { if(bit >= sizeof(IntType)CHAR_BIT) return false; flags &= ~(1 << bit); return true; } template <class IntType> bool Flag<IntType>::GetBit(Uint8 bit) { if((1 << bit) & flags) return true; return false; } template <class IntType> IntType Flag<IntType>::GetFlags() { return flags; } template <class IntType> void Flag<IntType>::PrintFlags() { int pos=1, bit=0; for(int i=0; i<sizeof(IntType)CHAR_BIT; i++) { ( pos & flags )? bit=1: bit=0; cout << bit; pos <<= 1; } cout << "\n"; } --v
