NAME

       X509_STORE_set_verify_cb_func, X509_STORE_set_verify_cb - set verifica-
       tion 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 corre-
       sponding X509_STORE_CTX structure when it is initialized. This can be
       used to set the verification callback when the X509_STORE_CTX is other-
       wise 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.
