X509_STORE_set_verify_cb_func(3SSL)                                   OpenSSL                                  X509_STORE_set_verify_cb_func(3SSL)

NAME
       X509_STORE_set_verify_cb_func, X509_STORE_set_verify_cb - set verification callback

SYNOPSIS
        #include <openssl/x509_vfy.h>

        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));

DESCRIPTION
       X509_STORE_set_verify_cb() sets the verification callback of ctx to verify_cb overwriting any existing callback.

       X509_STORE_set_verify_cb_func() also sets the verification callback but it is implemented as a macro.

NOTES
       The verification callback from an X509_STORE is inherited by the corresponding X509_STORE_CTX structure when it is initialized. This can be
       used to set the verification callback when the X509_STORE_CTX is otherwise inaccessible (for example during S/MIME verification).

BUGS
       The macro version of this function was the only one available before OpenSSL 1.0.0.

RETURN VALUES
       X509_STORE_set_verify_cb() and X509_STORE_set_verify_cb_func() do not return a value.

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.
