SSL_set_fd(3)
NAME
  SSL_set_fd - Connect the SSL object with a file descriptor

SYNOPSIS
  #include <openssl/ssl.h>

  int SSL_set_fd(
	  SSL *ssl, int fd );

  int SSL_set_rfd(
	  SSL *ssl, int fd );

  int SSL_set_wfd(
	  SSL *ssl, int fd );

DESCRIPTION
  The SSL_set_fd() function sets the file descriptor fd as the input/output
  facility for the TLS/SSL (encrypted) side of ssl. The fd will typically be
  the socket file descriptor of a network connection.

  When performing the operation, a socket BIO is automatically created to
  interface between the ssl and the fd. The BIO and the SSL engine inherit
  the behavior of fd. If fd is non-blocking, the ssl will also have non-
  blocking behavior.

  If there was already a BIO connected to ssl, the BIO_free() function will
  be called (for both the reading and writing side, if different).

  The SSL_set_rfd() and SSL_set_wfd() functions perform the respective
  action, but only for the read channel or the write channel, which can be
  set independently.

RETURN VALUES
  The following return values can occur:

  0	  The operation failed. Check the error stack to find out why.

  1	  The operation succeeded.
