The BIO and hence the SSL engine +inherit the behaviour of \fBfd\fR. If \fBfd\fR is nonblocking, the \fBssl\fR will +also have nonblocking behaviour. +.PP +When used on a QUIC connection SSL object, a \fBdatagram BIO\fR is automatically +created instead of a \fBsocket BIO\fR. These functions fail if called +on a QUIC stream SSL object. +.PP +If there was already a BIO connected to \fBssl\fR, \fBBIO_free()\fR will be called +(for both the reading and writing side, if different). +.PP +\&\fBSSL_set_rfd()\fR and \fBSSL_set_wfd()\fR perform the respective action, but only +for the read channel or the write channel, which can be set independently. +.SH "RETURN VALUES" +.IX Header "RETURN VALUES" +The following return values can occur: +.IP 0 4 +The operation failed. Check the error stack to find out why. +.IP 1 4 +.IX Item "1" +The operation succeeded. +.SH NOTES +.IX Header "NOTES" +On Windows, a socket handle is a 64\-bit data type (UINT_PTR), which leads to a +compiler warning (conversion from 'SOCKET' to 'int', possible loss of data) when +passing the socket handle to SSL_set_*\fBfd()\fR. For the time being, this warning can +safely be ignored, because although the Microsoft documentation claims that the +upper limit is INVALID_SOCKET\-1 (2^64 \- 2), in practice the current \fBsocket()\fR +implementation returns an index into the kernel handle table, the size of which +is limited to 2^24. +.SH "SEE ALSO" +.IX Header "SEE ALSO" +\&\fBSSL_get_fd\fR\|(3), \fBSSL_set_bio\fR\|(3), +\&\fBSSL_connect\fR\|(3), \fBSSL_accept\fR\|(3), +\&\fBSSL_shutdown\fR\|(3), \fBssl\fR\|(7) , \fBbio\fR\|(7) +.SH COPYRIGHT +.IX Header "COPYRIGHT" +Copyright 2000\-2023 The OpenSSL Project Authors.
