74dab6c2 208\fIBIO_s_socket()\fR returns the socket BIO method. This is a wrapper

209round the platform's socket routines.

211\fIBIO_read()\fR and \fIBIO_write()\fR read or write the underlying socket.

214If the close flag is set then the socket is shut down and closed
74dab6c2 215when the BIO is freed.
984263bc 216.PP
74dab6c2 217\fIBIO_set_fd()\fR sets the socket of BIO \fBb\fR to \fBfd\fR and the close

74dab6c2
JR
220\fIBIO_get_fd()\fR places the socket in \fBc\fR if it is not NULL, it also
221returns the socket. If \fBc\fR is not NULL it should be of type (int *).
984263bc 222.PP
74dab6c2 223\fIBIO_new_socket()\fR returns a socket BIO using \fBsock\fR and \fBclose_flag\fR.
984263bc 224.SH "NOTES"
984263bc
MD
225Socket BIOs also support any relevant functionality of file descriptor
226BIOs.
227.PP
228The reason for having separate file descriptor and socket BIOs is that on some
229platforms sockets are not file descriptors and use distinct I/O routines,
230Windows is one such platform. Any code mixing the two will not work on
231all platforms.
232.PP
74dab6c2 233\fIBIO_set_fd()\fR and \fIBIO_get_fd()\fR are macros.
984263bc 234.SH "RETURN VALUES"
74dab6c2 235\fIBIO_s_socket()\fR returns the socket BIO method.
984263bc 236.PP
74dab6c2 237\fIBIO_set_fd()\fR always returns 1.
984263bc 238.PP
74dab6c2 239\fIBIO_get_fd()\fR returns the socket or \-1 if the BIO has not been
984263bc
