5 SSL_get_fd, SSL_get_rfd, SSL_get_wfd - get file descriptor linked to an SSL object
9 #include <openssl/ssl.h>
11 int SSL_get_fd(const SSL *ssl);
12 int SSL_get_rfd(const SSL *ssl);
13 int SSL_get_wfd(const SSL *ssl);
17 SSL_get_fd() returns the file descriptor which is linked to B<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 descriptor
25 The following return values can occur:
31 The operation failed, because the underlying BIO is not of the correct type
32 (suitable for file descriptors).
36 The file descriptor linked to B<ssl>.
