Re: [libredwg] CRC?

[Till Heuschmann]

You can read the crc like this (classes section):

//ckr = bit_read_CRC(dat);
bit_check_CRC(dat, dwg->header.section[1].address + 16, 0xC0C1);

The function will read the crc but the comparison will fail due to an 
error in the function:
Just flip the bytes of one crc and the two crc are the same!

The magic thing is the bit_check_CRC functions parameter "seed" which 
must be in most sections 0xC0C1
but 0 in the SectionLocator!
