     _v_o_i_d
     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.

RREETTUURRNN VVAALLUUEESS
     The ffrreeee() function returns no value.

SSEEEE AALLSSOO
     calloc(3),  malloc(3),  realloc(3)

     The ffrreeee() function conforms to ANSI C X3.159-1989 (``ANSI C '').
