SSL_get_fd - get file descriptor linked to an SSL object


SYNOPSIS

        #include <openssl/ssl.h>

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