NAME

6       SSL_get_fd, SSL_get_rfd, SSL_get_wfd - get file descriptor linked to an
7       SSL object
8

SYNOPSIS

10        #include <openssl/ssl.h>
11
12        int SSL_get_fd(const SSL *ssl);
13        int SSL_get_rfd(const SSL *ssl);
14        int SSL_get_wfd(const SSL *ssl);
15

DESCRIPTION

17       SSL_get_fd() returns the file descriptor which is linked to ssl.
18       SSL_get_rfd() and SSL_get_wfd() return the file descriptors for the
19       read or the write channel, which can be different. If the read and the
20       write channel are different, SSL_get_fd() will return the file
21       descriptor of the read channel.
22

RETURN VALUES

24       The following return values can occur:
25
26       -1  The operation failed, because the underlying BIO is not of the
27           correct type (suitable for file descriptors).
28
29       >=0 The file descriptor linked to ssl.
