Re: [plt-scheme] Binary file access

["Sylvain Beucler"<sylvain.beucler.fac@libertysurf.fr>]

The code for binary reading was really interesting (I was
about to multiply each 'character' by 2^8, 2^16, etc,
while you used binary left shift on one byte and then
applied a OR to them).

I do not need to use float numbers, but I also checked
binary-io.c; I noticed though, that the u32_t hv_read_u32
function is not complete, and I could not find the
datatypes.h file needed for compiling. I am not very good
(even bad) using C so maybe I am wrong.

Now I just have to make Scheme write to files the same way
- or maybe just try to adapt
'integer->integer-byte-string' to v103 if this function
source is written in Scheme.


Thanks for the help,
