For a library designed to deal with the weirdness of binary file formats, I'm surprised it does not support 24-bit integers of arbitrary alignment/sign.

uint32_t x = raw_memory <uint32_t, big_endian>::peek (&vbBuffer [5]);

Do you also support a non-template "endianness" parameter? Sometimes you don't know the endian-style of the file until you open it and read some value out of it.   Joe
