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.
