135 .IX Header "SYNOPSIS"
137 \& #include <openssl/bio.h>
139 \& BIO_METHOD *BIO_s_socket(void);
141 \& long BIO_set_fd(BIO *b, int fd, long close_flag);
142 \& long BIO_get_fd(BIO *b, int *c);
144 \& BIO *BIO_new_socket(int sock, int close_flag);
147 .IX Header "DESCRIPTION"
148 \&\fIBIO_s_socket()\fR returns the socket \s-1BIO\s0 method. This is a wrapper
149 round the platform's socket routines.
151 \&\fIBIO_read()\fR and \fIBIO_write()\fR read or write the underlying socket.
152 \&\fIBIO_puts()\fR is supported but \fIBIO_gets()\fR is not.
154 If the close flag is set then the socket is shut down and closed
155 when the \s-1BIO\s0 is freed.
157 \&\fIBIO_set_fd()\fR sets the socket of \s-1BIO\s0 \fBb\fR to \fBfd\fR and the close
158 flag to \fBclose_flag\fR.
160 \&\fIBIO_get_fd()\fR places the socket in \fBc\fR if it is not \s-1NULL\s0, it also
161 returns the socket. If \fBc\fR is not \s-1NULL\s0 it should be of type (int *).
163 \&\fIBIO_new_socket()\fR returns a socket \s-1BIO\s0 using \fBsock\fR and \fBclose_flag\fR.
166 Socket BIOs also support any relevant functionality of file descriptor
169 The reason for having separate file descriptor and socket BIOs is that on some
170 platforms sockets are not file descriptors and use distinct I/O routines,
171 Windows is one such platform. Any code mixing the two will not work on
174 \&\fIBIO_set_fd()\fR and \fIBIO_get_fd()\fR are macros.
176 .IX Header "RETURN VALUES"
177 \&\fIBIO_s_socket()\fR returns the socket \s-1BIO\s0 method.
179 \&\fIBIO_set_fd()\fR always returns 1.
181 \&\fIBIO_get_fd()\fR returns the socket or \-1 if the \s-1BIO\s0 has not been
184 \&\fIBIO_new_socket()\fR returns the newly allocated \s-1BIO\s0 or \s-1NULL\s0 is an error
