.... Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. | will give a
real vertical bar. \*(C+ will give a nicer C++. Capital omega is used to
do unbreakable dashes and therefore won't be available. \*(C` and \*(C'
expand to `' in nroff, nothing in troff, for use with C<>.

If the F register is turned on, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.Sh), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.

Fear. Run. Save yourself. No user-serviceable parts.

Title "SSL_do_handshake 3"
.Vb 1 int SSL_do_handshake(SSL *ssl); .Ve
If the underlying \s-1BIO\s0 is blocking, SSL_do_handshake() will only return once the handshake has been finished or an error occurred, except for \s-1SGC\s0 (Server Gated Cryptography). For \s-1SGC\s0, SSL_do_handshake() may return with -1, but SSL_get_error() will yield \s-1SSL_ERROR_WANT_READ/WRITE\s0 and \fISSL_do_handshake() should be called again.
If the underlying \s-1BIO\s0 is non-blocking, SSL_do_handshake() will also return when the underlying \s-1BIO\s0 could not satisfy the needs of SSL_do_handshake() to continue the handshake. In this case a call to SSL_get_error() with the return value of SSL_do_handshake() will yield \s-1SSL_ERROR_WANT_READ\s0 or \fB\s-1SSL_ERROR_WANT_WRITE\s0. The calling process then must repeat the call after taking appropriate action to satisfy the needs of SSL_do_handshake(). The action depends on the underlying \s-1BIO\s0. When using a non-blocking socket, nothing is to be done, but select() can be used to check for the required condition. When using a buffering \s-1BIO\s0, like a \s-1BIO\s0 pair, data must be written into or retrieved out of the \s-1BIO\s0 before being able to continue.
