/* Mbedtls Test Info accessors
*
* NOTE - there are two types of accessors here: public accessors and internal
* accessors. The public accessors have prototypes in helpers.h and lock
* mbedtls_test_info_mutex (if mutexes are enabled). The _internal accessors,
* which are expected to be used from this module *only*, do not lock the mutex.
* These are designed to be called from within public functions which already
* hold the mutex. The main reason for this difference is the need to set
* multiple test data values atomically (without releasing the mutex) to prevent
* race conditions. */
