SSL_get_fd(3)                       OpenSSL                      SSL_get_fd(3)



NAME
       SSL_get_fd - get file descriptor linked to an SSL object

LIBRARY
       libcrypto, -lcrypto

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 descrip-
       tor of the read channel.

RETURN VALUES
       The following return values can occur:

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

       >=0 The file descriptor linked to ssl.
