[Boost-users] How to copy binary file to dynamic bitset?

Hello, I would like to try one-bit correlation between two one-bit sampling VLBI data files using powerful dynamic bitset library. (VLBI:Very Long Baseline Interferometer) A binary file japan.dat includes one-bit sampling data of a quasar received at a Japanese antenna and another binary file usa.dat includes one-bit sampling data of a same quasar received simultaneously at a US antenna. The bitset block size should be more than 10Mbits What kind of constructor codes should I write to copy the bit-pattern of each data file to each very long dynamic bitset? I am sorry but I could not find any good answer from Google search. I am looking forward to helpful answer in this mail-list. Very Thanks fuji
