SSL_get_fd(3)
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
  The SSL_get_fd() function returns the file descriptor which is linked to
  ssl. The SSL_get_rfd() and SSL_get_wfd() functions return the file
  descriptors for the read or the write channel, which can be different. If
  the read and the write channel are different, the SSL_get_fd() function
  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.
