=pod =head1 NAME X509_STORE_set_verify_cb_func, X509_STORE_set_verify_cb - set verification callback =head1 SYNOPSIS #include void X509_STORE_set_verify_cb(X509_STORE *st, int (*verify_cb)(int ok, X509_STORE_CTX *ctx)); void X509_STORE_set_verify_cb_func(X509_STORE *st, int (*verify_cb)(int ok, X509_STORE_CTX *ctx)); =head1 DESCRIPTION X509_STORE_set_verify_cb() sets the verification callback of B to B overwriting any existing callback. X509_STORE_set_verify_cb_func() also sets the verification callback but it is implemented as a macro. =head1 NOTES The verification callback from an B is inherited by the corresponding B structure when it is initialized. This can be used to set the verification callback when the B is otherwise inaccessible (for example during S/MIME verification). =head1 BUGS The macro version of this function was the only one available before OpenSSL 1.0.0. =head1 RETURN VALUES X509_STORE_set_verify_cb() and X509_STORE_set_verify_cb_func() do not return a value. =head1 SEE ALSO L L =head1 HISTORY X509_STORE_set_verify_cb_func() is available in all versions of SSLeay and OpenSSL. X509_STORE_set_verify_cb() was added to OpenSSL 1.0.0. =cut
