SSL_get_fd(3)                                OpenSSL                                SSL_get_fd(3)



NAME
       SSL_get_fd - get file descriptor linked to an SSL object

SYNOPSIS
        #include <openssl/ssl.h>

        int SSL_get_fd(const SSL *ssl);
        int SSL_get_rfd(const SSL *ssl);
        int SSL_get_wfd(const SSL *ssl);

DESCRIPTION
       SSL_get_fd() returns the file descriptor which is linked to ssl.  SSL_get_rfd() and
       SSL_get_wfd() return the file descriptors for the read or the write channel, which can be
       different. If the read and the write channel are different, SSL_get_fd() will return the
       file descriptor of the read channel.

RETURN VALUES
       The following return values can occur:

       -1  The operation failed, because the underlying BIO is not of the correct type (suitable
           for file descriptors).

       >=0 The file descriptor linked to ssl.
