156\&\fIX509_STORE_set_verify_cb()\fR sets the verification callback of \fBctx\fR to
157\&\fBverify_cb\fR overwriting any existing callback.
158.PP
159\&\fIX509_STORE_set_verify_cb_func()\fR also sets the verification callback but it
160is implemented as a macro.

163The verification callback from an \fBX509_STORE\fR is inherited by
164the corresponding \fBX509_STORE_CTX\fR structure when it is initialized. This can
165be used to set the verification callback when the \fBX509_STORE_CTX\fR is
166otherwise inaccessible (for example during S/MIME verification).
