NAME

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.
