bitmap indexes in c++

HI!! i have to develop an documental data base and i have to implement bitmap indexes...
As you may know, the leaf nodes of the b-tree + have a pointer to an array of 0 and 1....
Can it be an standar size 64KB ?? Does c++ provide me a class to do this? If can i do an array o 0 and 1...but not an bit field....because what i need to do is for instance:
vector[3] =1; vector[7]=0; if(vector[6]==0) do();
NOte: i am using suse 10 and kdevelop
