When using the Sockets function 'recv', if I give it a length
parameter of 30001 it returns an error of EINVAL, although 30000 is
fine.

Is this number defined somewhere? It doesn't seem to be in the
documentation, and I haven't found any reference to it on the
internet. I'm trying to write portable code, so I don't want to use a
hard coded value of 30000 only to find some other system has a lower
limit.

Any ideas?

(By the way, I'm compiling using c89 in the posix shell).
