Some caveats. The NewBinary library contains two things:
(1) A uniform interface for reading and writing binary files and
binary memory, including bitwise reading/writing.
(2) A Binary class for serialization/deserialization
While it is tempting to use the functions in the Binary class (put/get),
it is important to realize that they do not care about big endian vs
little endian. Nor do they attempt to be compatible with equivalent
C data types. For example, Char is stored as 4 bytes.
However, while the Binary class in NewBinary may not be appropriate,
the uniform interface to binary files/memory could be a good foundation
for building hGetWord16le, hGetWord16be, etc.
If you submitted a module that added these functions, I would be glad
to update the archive.
