# libressl-SSL\_set\_SSL\_CTX(3)

modify an SSL connection object to use another context

## NAME

**SSL\_set\_SSL\_CTX** – modify an SSL connection object to use another context

## SYNOPSIS

SSL Library (libssl, -lssl) libcrypto

**#include \<openssl/ssl.h\>**

*SSL\_CTX* *\**\

**SSL\_set\_SSL\_CTX**(*SSL \*ssl*, *SSL\_CTX\* ctx*);

## DESCRIPTION

**SSL\_set\_SSL\_CTX**() causes *ssl* to use the context *ctx*.

If *ctx* is NULL, *ssl* reverts to using the context that it was initially created from with SSL\_new(3).

If *ssl* already uses *ctx*, no action occurs.

## RETURN VALUES

**SSL\_set\_SSL\_CTX**() returns an internal pointer to the context that *ssl* is using as a result of the call, or NULL if memory allocation fails.

## HISTORY

**SSL\_set\_SSL\_CTX**() first appeared in OpenSSL 0.9.8f and has been available since OpenBSD 4.5.
