62  ** m_whowas   *
63  **      parv[0] = sender prefix   * \param client_p Pointer to allocated Client struct with physical connection
64  **      parv[1] = nickname queried   *                 to this server, i.e. with an open socket connected.
65  */   * \param source_p Pointer to allocated Client struct from which the message
66     *                 originally comes from.  This can be a local or remote client.
67     * \param parc     Integer holding the number of supplied arguments.
68     * \param parv     Argument vector where parv[0] .. parv[parc-1] are non-NULL
69     *                 pointers.
70     * \note Valid arguments for this command are:
71     *      - parv[0] = sender prefix
72     *      - parv[1] = nick
73     *      - parv[2] = count (optional; limited to 20 for remote requests)
74     *      - parv[3] = name of target (optional; string can be a nick or server
75     *                  and can also include wildcards)
