NAME
     tt_session_propname - returns an element of the list of pro-
     perty names for a session

SYNOPSIS
     #include <Tt/tt_c.h>
     char *tt_session_propname(const char *sessid,
                               int n);

DESCRIPTION
     The tt_session_propname() function returns the  nth  element
     of  the  list  of  currently  defined property names for the
     specified session.

     The sessid argument is the name of the session joined.   The
     application   can   use   the  sessid  value  returned  when
     tt_default_session() is  called.   The  n  argument  is  the
     number  of  the  item  in the property name list for which a
     name is to be obtained.   The  list  numbering  begins  with
     zero.

RETURN VALUE
     Upon successful completion, the tt_session_propname()  func-
     tion  returns  the  name  of the specified property from the
     session property list.  If there are n properties or  fewer,
     tt_session_propname() returns NULL.  The application can use
     tt_ptr_error(3) to extract one of  the  following  Tt_status
     values from the returned pointer:

        TT_OK   The operation completed successfully.

                The specified ToolTalk session is out of date  or
                invalid.
