157 descriptor \fBfd\fR to the specified \s-1SSL\s0 connection \fBs\fR. This function provides
158 efficient zero-copy semantics. \fBSSL_sendfile()\fR is available only when
159 Kernel \s-1TLS\s0 is enabled, which can be checked by calling \fBBIO_get_ktls_send()\fR.
168 If necessary, a write function will negotiate a \s-1TLS/SSL\s0 session, if not already

172 underlying \s-1BIO.\s0
179 If the underlying \s-1BIO\s0 is \fBblocking\fR, the write functions will only return, once
182 If the underlying \s-1BIO\s0 is \fBnonblocking\fR the write functions will also return
183 when the underlying \s-1BIO\s0 could not satisfy the needs of the function to continue
185 return value of the write function will yield \fB\s-1SSL_ERROR_WANT_READ\s0\fR
186 or \fB\s-1SSL_ERROR_WANT_WRITE\s0\fR. As at any time a re-negotiation is possible, a

218 if \s-1SSL_MODE_ENABLE_PARTIAL_WRITE\s0 is in use, at least 1 application data byte has
