** FUNCTION: PR_Select
** DESCRIPTION:
**
** The call returns as soon as I/O is ready on one or more of the underlying
** file/socket descriptors or an exceptional condition is pending. A count of the
** number of ready descriptors is returned unless a timeout occurs in which case
** zero is returned. On return, PR_Select replaces the given descriptor sets with
** subsets consisting of those descriptors that are ready for the requested condition.
** The total number of ready descriptors in all the sets is the return value.
**
** INPUTS:
** PRInt32 num
** This argument is unused but is provided for select(unix) interface
** compatability. All input PR_fd_set arguments are self-describing
** with its own maximum number of elements in the set.
**
** PR_fd_set *readfds
** A set describing the io descriptors for which ready for reading
** condition is of interest.
**
** PR_fd_set *writefds
** A set describing the io descriptors for which ready for writing
** condition is of interest.
**
** PR_fd_set *exceptfds
** A set describing the io descriptors for which exception pending
** condition is of interest.
**
** Any of the above readfds, writefds or exceptfds may be given as NULL
** pointers if no descriptors are of interest for that particular condition.
**
** PRIntervalTime timeout
** Amount of time the call will block waiting for I/O to become ready.
** If this time expires without any I/O becoming ready, the result will
** be zero.
**
** OUTPUTS:
** PR_fd_set *readfds
** A set describing the io descriptors which are ready for reading.
**
** PR_fd_set *writefds
** A set describing the io descriptors which are ready for writing.
**
** PR_fd_set *exceptfds
** A set describing the io descriptors which have pending exception.
**
** RETURN:PRInt32
** Number of io descriptors with asked for conditions or zero if the function
** timed out or -1 on failure. The reason for the failure is obtained by
** calling PR_GetError().
** XXX can we implement this on windoze and mac?
