Availability:C-language interface function
void PL_free_term_ref(term_t
t)Release a specific term reference. Normally all term references in a
scope are discarded together or all term references created
after a specific one are reclaimed using PL_reset_term_refs().
This function shrinks the current foreign frame if t is the
last one in the frame. Else it marks t for reuse by PL_new_term_ref().
