SSL_SET_FD(3)                OpenSSL                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

     SSL_set_fd() sets the file descriptor fd as the input/output
     facility for the TLS/SSL (encrypted) side of ssl. fd will
     typically be the socket file descriptor of a network connec-
     tion.

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

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

     SSL_set_rfd() and SSL_set_wfd() 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.
