Description

       Set or gets the optional application callback (and the callback argument) that is called during self
       testing.  The application callback OSSL_CALLBACK(3) is associated with a OSSL_LIB_CTX.  The application
       callback function receives information about a running self test, and may return a result to the calling
       self test.  See openssl-core.h(7) for further information on the callback.

History

       The functions described here were added in OpenSSL 3.0.

Name

       OSSL_SELF_TEST_set_callback, OSSL_SELF_TEST_get_callback - specify a callback for processing self tests

Return Values

OSSL_SELF_TEST_get_callback() returns the callback and callback argument that has been set via
       OSSL_SELF_TEST_set_callback() for the given library context ctx.  These returned parameters will be NULL
       if OSSL_SELF_TEST_set_callback() has not been called.

Synopsis
