SSL_get_fd - get file descriptor linked to an SSL object

CONTENTS

 #include <openssl/ssl.h>

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

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.

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.

SSL_set_fd(3), ssl(3) , bio(3)
