       const char *p_group
              Group name if any.

       const char *p_name
              Name of tag.

       ...    Subequent qualifiers.

DESCRIPTION

       Basic searching function locating elements of the VOBJECT by qualified name.  The function
       is a varargs function (like sprintf) and the list of arguments  must  be  NULL  terminated
       (hence the appearance of the p_qualifier argument in the arglist).  Valid calls might be:

       vf_get_property(&p_out, p_object, VFGP_FIND, NULL, "N", NULL);
       - Find and return "N" properties.  If there are none, return FALSE.

       Vf_get_property(&p_out, p_object, VFGP_FIND, NULL, "TEL", "WORK", NULL);
       -  Find  and  return  "TEL"  entries  qualified  by  the  "work" attribute (ie. Work phone
       numbers). If there are none, return FALSE.

       Vf_get_property(&p_out, p_object, VFGP_GET, NULL, "TEL", "WORK", NULL);
       - Find and return work phone number.   The  entry  is  automatically  added  if  not  pre-
       existing.

       Vf_get_property(&p_out, p_object, VFGP_GET, NULL, "TEL", "WORK", NULL);
       -  Find and return work phone numbers in the group identifier by the "ME" identifier.  The
       entry is automatically added if not pre-existing.

       Vf_get_property(&p_out, p_object, VFGP_FIND, "ME", "*", NULL);
       - Effectively enumerates all entries in the "ME" group.

       A pointer to the first property matching the search criteria is returned via  the  pp_prop
       argument.   The search actually locates all such matches and pointer to subsequent entries
       (if there are >1) may be found by calling the vf_get_next_property() function.

       The tags may occur in any order _except_ that the p_name must be first.

       Note that the  VF_PROP_T  returned  by  pp_prop  is  an  opaque  type  and  the  functions
       vf_get_prop_xxxx() etc. Must be used to locate real "values".

       Cached    search   results   (the   list   enumerated   by   subsequent   calls   to   the
       vf_get_next_property() function) are maintained through the use of  a  a  single  internal
       pointer therefore this method is not thread safe.

RETURNS

       TRUE iff found/added successfully.  Ptr to prop returned via pp_prop.
