SYNOPSIS
     #include <Tt/tt_c.h>
     char *tt_spec_prop(const char *objid,
                        const char *propname,
                        int i);

DESCRIPTION
     The tt_spec_prop() function retrieves the ith value of the property
     associated with this object spec.

     The objid argument is the identifier of the object involved in this
     operation.  The propname argument is the name of the property associated
     with the object spec.  The i argument is the item of the list whose value
     is to be retrieved.  The list numbering begins with zero.

RETURN VALUE
     Upon successful completion, the tt_spec_prop() function returns the
     contents of the property value.  If there are i values or less,
     tt_spec_prop() returns NULL.  The application can use tt_ptr_error(3) to
     extract one of the following Tt_status values from the returned pointer:
