+** 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?
