206 \fISSL_CTX_set_mode()\fR adds the mode set via bitmask in \fBmode\fR to \fBctx\fR.
207 Options already set before are not cleared.
209 \fISSL_set_mode()\fR adds the mode set via bitmask in \fBmode\fR to \fBssl\fR.
210 Options already set before are not cleared.
212 \fISSL_CTX_get_mode()\fR returns the mode set for \fBctx\fR.
214 \fISSL_get_mode()\fR returns the mode set for \fBssl\fR.
216 The following mode changes are available:
217 .Ip "\s-1SSL_MODE_ENABLE_PARTIAL_WRITE\s0" 4
218 Allow \fISSL_write\fR\|(..., n) to return r with 0 < r < n (i.e. report success
219 when just a single record has been written). When not set (the default),
220 \fISSL_write()\fR will only report success once the complete chunk was written.
221 Once \fISSL_write()\fR returns with r, r bytes have been successfully written
222 and the next call to \fISSL_write()\fR must only send the n-r bytes left,
223 imitating the behaviour of \fIwrite()\fR.
224 .Ip "\s-1SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER\s0" 4
225 Make it possible to retry \fISSL_write()\fR with changed buffer location
226 (the buffer contents must stay the same). This is not the default to avoid
227 the misconception that non-blocking \fISSL_write()\fR behaves like
228 non-blocking \fIwrite()\fR.
229 .Ip "\s-1SSL_MODE_AUTO_RETRY\s0" 4
230 Never bother the application with retries if the transport is blocking.
231 If a renegotiation take place during normal operation, a
232 SSL_read(3) or SSL_write(3) would return
233 with \-1 and indicate the need to retry with \s-1SSL_ERROR_WANT_READ\s0.
234 In a non-blocking environment applications must be prepared to handle
235 incomplete read/write operations.
236 In a blocking environment, applications are not always prepared to
237 deal with read/write operations returning without success report. The
238 flag \s-1SSL_MODE_AUTO_RETRY\s0 will cause read/write operations to only
239 return after the handshake and successful completion.
241 \fISSL_CTX_set_mode()\fR and \fISSL_set_mode()\fR return the new mode bitmask
242 after adding \fBmode\fR.
244 \fISSL_CTX_get_mode()\fR and \fISSL_get_mode()\fR return the current bitmask.
