|  | =head1 NAME | 
|  |  | 
|  | OSSL_SELF_TEST_set_callback, | 
|  | OSSL_SELF_TEST_get_callback - specify a callback for processing self tests | 
|  |  | 
|  | =head1 SYNOPSIS | 
|  |  | 
|  | #include <openssl/self_test.h> | 
|  |  | 
|  | void OSSL_SELF_TEST_set_callback(OPENSSL_CTX *ctx, OSSL_CALLBACK *cb, void *cbarg); | 
|  | void OSSL_SELF_TEST_get_callback(OPENSSL_CTX *ctx, OSSL_CALLBACK **cb, void **cbarg); | 
|  |  | 
|  | =head1 DESCRIPTION | 
|  |  | 
|  | Set or gets the optional application callback (and the callback argument) that | 
|  | is called during self testing. | 
|  | The application callback B<OSSL_CALLBACK> is associated with a B<OPENSSL_CTX>. | 
|  | The application callback function receives information about a running self test, | 
|  | and may return a result to the calling self test. | 
|  | See L<openssl-core.h(7)> for further information on the callback. | 
|  |  | 
|  | =head1 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 B<ctx>. | 
|  | These returned parameters will be NULL if OSSL_SELF_TEST_set_callback() has | 
|  | not been called. |
