* \file mbedtls/config_adjust_ssl.h
|
|
* \brief Adjust TLS configuration
|
|
*
|
|
* This is an internal header. Do not include it directly.
|
|
*
|
|
* Automatically enable certain dependencies. Generally, MBEDTLS_xxx
|
|
* configurations need to be explicitly enabled by the user: enabling
|
|
* MBEDTLS_xxx_A but not MBEDTLS_xxx_B when A requires B results in a
|
|
* compilation error. However, we do automatically enable certain options
|
|
* in some circumstances. One case is if MBEDTLS_xxx_B is an internal option
|
|
* used to identify parts of a module that are used by other module, and we
|
|
* don't want to make the symbol MBEDTLS_xxx_B part of the public API.
|
|
* Another case is if A didn't depend on B in earlier versions, and we
|
|
* want to use B in A but we need to preserve backward compatibility with
|
|
* configurations that explicitly activate MBEDTLS_xxx_A but not
|
|
* MBEDTLS_xxx_B.
