I should specify something called Block/BlockInputIterator as a template parameter? I do not know what that is.
Playing around a little more made me realize that the following is ok: unsigned char data[5] = {211,14,97,42,31}; boost::dynamic_bitset<unsigned char> bitbuf(data,&data[5]); So, unsigned char specifies a Block and the unsigned char* is the BlockInputIterator - alright. It wasn't that obvious for me as a newbie...
After construction I do not see how to extract the bits!? Is it only possible to extract one bit at a time?!?!?
I have not find a way around this yet :-( To make myself clear, I'd like to extract a range of bits, preferably by specifing the start bit position and the number of bits to extract. I can see that there is a to_block_range but it just extracts the complete bitset. Now, another issue has surfaced. When iterating the bitset I see that the bits are stored in a "weird" format (at least it is weird to me)?! for (int i=0; i<5*8; ++i) { bool bit_i = bitbuf[i]; std::cout << bit_i; } Instead of the expected sequence: 1101001100001110011000010010101000011111 the loop prints: 1100101101110000100001100101010011111000 I.e. each byte has its bits in the reversed order! As a newbie it is not obvious to me why this is so... And the confusion is total after this: std::cout << bitbuf; which decides to print the sequence: 0001111100101010011000010000111011010011 Please help me figure the rationale behind this out!
