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