.Sh DESCRIPTION
|
|
.Fn X509_STORE_set_verify_cb
|
|
sets the verification callback of
|
|
.Sy ctx
|
|
to
|
|
.Sy verify_cb ,
|
|
overwriting any existing callback.
|
|
.Pp
|
|
.Fn X509_STORE_set_verify_cb_func
|
|
also sets the verification callback but it is implemented as a macro.
|
|
.Pp
|
|
The verification callback from an
|
|
.Vt X509_STORE
|
|
is inherited by the corresponding
|
|
.Vt X509_STORE_CTX
|
|
structure when it is initialized.
|
|
This can be used to set the verification callback when the
|
|
.Vt X509_STORE_CTX
|
|
is otherwise inaccessible (for example during S/MIME verification).
|
|
.Sh RETURN VALUES
|
|
.Fn X509_STORE_get_verify_cb
|
|
returns the function pointer set with
|
|
.Fn X509_STORE_set_verify_cb ,
|
|
or
|
|
.Dv NULL
|
|
if that function was not called on
