SSL_CTX_set_mode(3)			     OpenSSL			      SSL_CTX_set_mode(3)

NAME
       SSL_CTX_set_mode, SSL_set_mode, SSL_CTX_get_mode, SSL_get_mode - manipulate SSL engine
       mode

SYNOPSIS
	#include <openssl/ssl.h>

	long SSL_CTX_set_mode(SSL_CTX *ctx, long mode);
	long SSL_set_mode(SSL *ssl, long mode);

	long SSL_CTX_get_mode(SSL_CTX *ctx);
	long SSL_get_mode(SSL *ssl);

DESCRIPTION
       SSL_CTX_set_mode() adds the mode set via bitmask in mode to ctx.  Options already set
       before are not cleared.

       SSL_set_mode() adds the mode set via bitmask in mode to ssl.  Options already set before
       are not cleared.

       SSL_CTX_get_mode() returns the mode set for ctx.

       SSL_get_mode() returns the mode set for ssl.

NOTES
       The following mode changes are available:

       SSL_MODE_ENABLE_PARTIAL_WRITE
	   Allow SSL_write(..., n) to return r with 0 < r < n (i.e. report success when just a
	   single record has been written). When not set (the default), SSL_write() will only
	   report success once the complete chunk was written.	Once SSL_write() returns with r,
	   r bytes have been successfully written and the next call to SSL_write() must only send
	   the n-r bytes left, imitating the behaviour of write().

       SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER
	   Make it possible to retry SSL_write() with changed buffer location (the buffer con-
	   tents must stay the same). This is not the default to avoid the misconception that
	   non-blocking SSL_write() behaves like non-blocking write().

       SSL_MODE_AUTO_RETRY
	   Never bother the application with retries if the transport is blocking.  If a renego-
	   tiation take place during normal operation, a SSL_read(3) or SSL_write(3) would return
	   with -1 and indicate the need to retry with SSL_ERROR_WANT_READ.  In a non-blocking
	   environment applications must be prepared to handle incomplete read/write operations.
	   In a blocking environment, applications are not always prepared to deal with
	   read/write operations returning without success report. The flag SSL_MODE_AUTO_RETRY
	   will cause read/write operations to only return after the handshake and successful
	   completion.

RETURN VALUES
       SSL_CTX_set_mode() and SSL_set_mode() return the new mode bitmask after adding mode.

       SSL_CTX_get_mode() and SSL_get_mode() return the current bitmask.
