     _F_r_e_a_d reads, into a block beginning at _p_t_r, _n_i_t_e_m_s of data
     of the type of *_p_t_r from the named input _s_t_r_e_a_m.  It returns
     the number of items actually read.

     If _s_t_r_e_a_m is ssttddiinn and the standard output is line buffered,
     then any partial output line will be flushed before any call
     to _r_e_a_d(2) to satisfy the _f_r_e_a_d.

     _F_w_r_i_t_e appends at most _n_i_t_e_m_s of data of the type of *_p_t_r
     beginning at _p_t_r to the named output _s_t_r_e_a_m.  It returns the
     number of items actually written.
