Hi All!

There is a check for FD_SETSIZE in _PR_MD_PR_POLL()
function (w32poll.c):

if ((nrd > FD_SETSIZE) || (nwt > FD_SETSIZE) || (nex > FD_SETSIZE)) {
     PR_SetError(PR_INVALID_ARGUMENT_ERROR, 0);
     return -1;
}

and I am not sure what is the purpose of this check. It seems
like the WinSock select() function has no restriction on the
number of sockets passed in. Could you please clarify this?

Thanks
