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.
