Scott Olsen	05ab70b196	Add UintN->Byte conversions ... Note that we do not need an unsafe variant of these conversions since they are simple projections to and from the Uint types.	2020-02-18 13:35:35 -05:00
Scott Olsen	4faa721e1d	Add a function for retrieving the system endianness ... The technique here feels a bit hacky, but it's the common way to do it. We exploit the fact that ints are 16bits and chars are 8bits to grab the first byte in a systems int representation, which is indicative of its endianness.	2020-02-17 15:38:55 -05:00
Scott Olsen	ea1505779d	Add Binary module ... The binary module implements functions for interpreting byte sequences as int16, int32, or int64 values depending on a given endianess (the Byte module implements support for interpreting bytes as int8 values). It'd be nice if we could implement these functions in pure Carp, using the Bytes module--but unfortunately we need to rely on some type conversions in C, which are only possible by registering C functions for performing the necessary conversions. At the moment, all of these functions are unsafe (they access byte arrays using unsafe-nth).	2020-02-16 15:15:54 -05:00
