ffrreeee(_v_o_i_d _*_p_t_r)
DDEESSCCRRIIPPTTIIOONN
The ffrreeee() function causes the space pointed to by _p_t_r to be deallocated,
that is, made available for further allocation. If _p_t_r is a null point¡
er, no action occurs. Otherwise, if the argument does not match a point¡
er earlier returned by the calloc, malloc, or realloc function, or if
the space has been deallocated by a call to ffrreeee() or realloc, general
havoc may occur.
