132 .TH SSL_get_fd 3 "2007-03-28" "0.9.8e" "OpenSSL"
134 SSL_get_fd \- get file descriptor linked to an SSL object
136 .IX Header "SYNOPSIS"
138 \& #include <openssl/ssl.h>
142 \& int SSL_get_fd(const SSL *ssl);
143 \& int SSL_get_rfd(const SSL *ssl);
144 \& int SSL_get_wfd(const SSL *ssl);
147 .IX Header "DESCRIPTION"
148 \&\fISSL_get_fd()\fR returns the file descriptor which is linked to \fBssl\fR.
149 \&\fISSL_get_rfd()\fR and \fISSL_get_wfd()\fR return the file descriptors for the
150 read or the write channel, which can be different. If the read and the
151 write channel are different, \fISSL_get_fd()\fR will return the file descriptor
154 .IX Header "RETURN VALUES"
155 The following return values can occur:
158 The operation failed, because the underlying \s-1BIO\s0 is not of the correct type
159 (suitable for file descriptors).
162 The file descriptor linked to \fBssl\fR.
