On Solaris 9, SO_RCVTIMEO is not mentioned in the setsockopt man page.
My reading tells me that it is defined in the header file, but if it's
actually used, setsockopt() will return an error. I understand that
this is the case for other operating systems too. This seems to be a
known problem with setsockopt(). I just checked the Opensolaris source;
it does function there. This is the code:
if (optlen == sizeof (uint32_t))
sockets[i].in_timeout = *(uint32_t *)optval;
errno = EINVAL;
Note that the option has to be an int, and the length has to be
that of an int as well. Linux wants a `struct timeval'. I wonder
if there's a standard in this area?
