# SSL\_CONF\_CTX\_set\_ssl\_ctx(3ssl)

set context to configure

## NAME

SSL\_CONF\_CTX\_finish, SSL\_CONF\_CTX\_set\_ssl\_ctx, SSL\_CONF\_CTX\_set\_ssl - set context to configure

## SYNOPSIS

```
 #include <openssl/ssl.h>
 void SSL_CONF_CTX_set_ssl_ctx(SSL_CONF_CTX *cctx, SSL_CTX *ctx);
 void SSL_CONF_CTX_set_ssl(SSL_CONF_CTX *cctx, SSL *ssl);
 int SSL_CONF_CTX_finish(SSL_CONF_CTX *cctx);
```

## DESCRIPTION

**SSL\_CONF\_CTX\_set\_ssl\_ctx()** sets the context associated with **cctx** to the **SSL\_CTX** structure **ctx**. Any previous **SSL** or **SSL\_CTX** associated with **cctx** is cleared. Subsequent calls to **SSL\_CONF\_cmd()** will be sent to **ctx**.

**SSL\_CONF\_CTX\_set\_ssl()** sets the context associated with **cctx** to the **SSL** structure **ssl**. Any previous **SSL** or **SSL\_CTX** associated with **cctx** is cleared. Subsequent calls to **SSL\_CONF\_cmd()** will be sent to **ssl**.

The function **SSL\_CONF\_CTX\_finish()** must be called after all configuration operations have been completed. It is used to finalise any operations or to process defaults.

## NOTES

The context need not be set or it can be set to **NULL** in which case only syntax checking of commands is performed, where possible.

## RETURN VALUES

**SSL\_CONF\_CTX\_set\_ssl\_ctx()** and **SSL\_CTX\_set\_ssl()** do not return a value.

**SSL\_CONF\_CTX\_finish()** returns 1 for success and 0 for failure.

## HISTORY

These functions were added in OpenSSL 1.0.2.
