.. 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. \*(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<>.

Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Title "SSL_SET_RETRY_VERIFY 3ossl"
SSL_SET_RETRY_VERIFY 3ossl "2023-09-19" "3.0.11" "OpenSSL"
For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
"NAME"
SSL_set_retry_verify - indicate that certificate verification should be retried
"SYNOPSIS"
Header "SYNOPSIS" .Vb 1 #include <openssl/ssl.h> \& int SSL_set_retry_verify(SSL *ssl); .Ve
"DESCRIPTION"
Header "DESCRIPTION" \fBSSL_set_retry_verify() should be called from the certificate verification callback on a client when the application wants to indicate that the handshake should be suspended and the control should be returned to the application. \fBSSL_want_retry_verify\|(3) will return 1 as a consequence until the handshake is resumed again by the application, retrying the verification step.

Please refer to SSL_CTX_set_cert_verify_callback\|(3) for further details.

"NOTES"
Header "NOTES" The effect of calling SSL_set_retry_verify() outside of the certificate verification callback on the client side is undefined.
"RETURN VALUES"
Header "RETURN VALUES" SSL_set_retry verify() returns 1 on success, 0 otherwise.
"EXAMPLES"
Header "EXAMPLES" The following code snippet shows how to obtain the \s-1SSL\s0 object associated with the X509_STORE_CTX to call the SSL_set_retry_verify() function:

.Vb 2 int idx = SSL_get_ex_data_X509_STORE_CTX_idx(); SSL *ssl; \& /* this should not happen but check anyway */ if (idx < 0 || (ssl = X509_STORE_CTX_get_ex_data(ctx, idx)) == NULL) return 0; \& if (/* we need to retry verification callback */) return SSL_set_retry_verify(ssl); \& /* do normal processing of the verification callback */ .Ve

"SEE ALSO"
Header "SEE ALSO" \fBssl\|(7), SSL_connect\|(3), SSL_CTX_set_cert_verify_callback\|(3), \fBSSL_want_retry_verify\|(3)
"HISTORY"
Header "HISTORY" \fBSSL_set_retry_verify() was added in OpenSSL 3.0.2 to replace backwards incompatible handling of a negative return value from the verification callback.
