I may have just opened a real can of worms in my ignorance.
The reason I was trying out XDR is that I will soon have a need to
exchange float and double data between FreeBSD, Solaris, VMS, AIX, and
SGI.
The code in src/lib/libc/xdr/xdr_float.c seems to use this approach (when
IEEEFP is defined); treating float as two longs. The first test will be
between FBSD and the Sun system I am hooked to.
I have no experience in VMS, AIX, or SGI. Isn't XDR a Sun protocol that
wasn't picked up in the standards battles of the past few years. Or is it
one that is generally accepted? Is there an RFC that covers this?
