144 SSL_get_fd \- get file descriptor linked to an SSL object
148 .IX Header "SYNOPSIS"
150 \& #include <openssl/ssl.h>
152 \& int SSL_get_fd(const SSL *ssl);
153 \& int SSL_get_rfd(const SSL *ssl);
154 \& int SSL_get_wfd(const SSL *ssl);
157 .IX Header "DESCRIPTION"
158 \&\fISSL_get_fd()\fR returns the file descriptor which is linked to \fBssl\fR.
159 \&\fISSL_get_rfd()\fR and \fISSL_get_wfd()\fR return the file descriptors for the
160 read or the write channel, which can be different. If the read and the
161 write channel are different, \fISSL_get_fd()\fR will return the file descriptor
164 .IX Header "RETURN VALUES"
165 The following return values can occur:
168 The operation failed, because the underlying \s-1BIO\s0 is not of the correct type
169 (suitable for file descriptors).
172 The file descriptor linked to \fBssl\fR.
