Options already set before are not cleared. SSL_set_mode() adds the mode set via bitmask in B<mode> to B<ssl>. Options already set before are not cleared. SSL_CTX_get_mode() returns the mode set for B<ctx>. SSL_get_mode() returns the mode set for B<ssl>. =head1 NOTES The following mode changes are available: =over 4 =item 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. =item SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Make it possible to retry SSL_write() with changed buffer location (the buffer contents must stay the same). This is not the default to avoid the misconception that non-blocking SSL_write() behaves like non-blocking write(). =item SSL_MODE_AUTO_RETRY Never bother the application with retries if the transport is blocking. If a renegotiation take place during normal operation, a L<SSL_read(3)|SSL_read(3)> or L<SSL_write(3)|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. =back =head1 RETURN VALUES SSL_CTX_set_mode() and SSL_set_mode() return the new mode bitmask after adding B<mode>.
