       _B_I_O___s___s_o_c_k_e_t_(_) returns the socket BIO method. This is a wrapper round
       the platform's socket routines.

       _B_I_O___r_e_a_d_(_) and _B_I_O___w_r_i_t_e_(_) read or write the underlying socket.
       _B_I_O___p_u_t_s_(_) is supported but _B_I_O___g_e_t_s_(_) is not.

       If the close flag is set then the socket is shut down and closed when
       the BIO is freed.

       _B_I_O___s_e_t___f_d_(_) sets the socket of BIO bb to ffdd and the close flag to
       cclloossee__ffllaagg.

       _B_I_O___g_e_t___f_d_(_) places the socket in cc if it is not NULL, it also returns
       the socket. If cc is not NULL it should be of type (int *).

       _B_I_O___n_e_w___s_o_c_k_e_t_(_) returns a socket BIO using ssoocckk and cclloossee__ffllaagg.

       Socket BIOs also support any relevant functionality of file descriptor
       BIOs.

       The reason for having separate file descriptor and socket BIOs is that
       on some platforms sockets are not file descriptors and use distinct I/O
       routines, Windows is one such platform. Any code mixing the two will
       not work on all platforms.

       _B_I_O___s_e_t___f_d_(_) and _B_I_O___g_e_t___f_d_(_) are macros.

       _B_I_O___s___s_o_c_k_e_t_(_) returns the socket BIO method.

       _B_I_O___s_e_t___f_d_(_) always returns 1.

       _B_I_O___g_e_t___f_d_(_) returns the socket or -1 if the BIO has not been initial-
       ized.

       _B_I_O___n_e_w___s_o_c_k_e_t_(_) returns the newly allocated BIO or NULL is an error
       occurred.
