NAME
     tt_session_bprop - retrieve the ith value of the named property of a
     session

SYNOPSIS
     #include <Tt/tt_c.h>
     Tt_status tt_session_bprop(const char *sessid,
                                const char *propname,
                                int i,
                                unsigned char **value,
                                int *length);

DESCRIPTION
     The tt_session_bprop() function retrieves the ith value of the named
     property of the specified session.

     If there are i values or fewer, both the returned value and the returned
     length are set to zero.

     The sessid argument is the session joined.  The application can use the
     sessid value returned when tt_default_session() is called.  The propname
     argument is the name of the property from which values are to be
     obtained.  The i argument is the number of the item in the property list
     from which the value is to be obtained.  The list numbering begins with
     zero.  The value argument is the address of a character pointer to which
     the ToolTalk service is to point a string that contains the contents of
     the property.  The len argument is the address of an integer to which the
     ToolTalk service is to set the length of the value in bytes.

     status of the operation as one of the following Tt_status values:
