Could be a good thing to check the facts. From des_locl.h:
[...]
#define c2l(c,l) (l =((DES_LONG)(*((c)++))) , \
l|=((DES_LONG)(*((c)++)))<< 8L, \
l|=((DES_LONG)(*((c)++)))<<16L, \
l|=((DES_LONG)(*((c)++)))<<24L)
[...]
The first argument is definitely being changed. What is weird,
though, is that des_cblock is basically an array of char, thus making
in a char pointer, but I assume this is a declaration technicality in
ANSI C. As it is declared right now ("const des_cblock in"), it
probably means that in itself is a constant, possibly as well as the
contents of the array. Unfortunately, I do not have the ANSI C spec.
handy, so I can't verify this...
