The application callback <b>OSSL_CALLBACK</b> is associated with a <b>OSSL_LIB_CTX</b>. The application callback function receives information about a running self test, and may return a result to the calling self test. See <a href="../man7/openssl-core.h.html">openssl-core.h(7)</a> for further information on the callback.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>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 <i>ctx</i>.
