<P>
<CODE>X509_STORE_set_verify_cb()</CODE> sets the verification callback of <STRONG>ctx</STRONG> to
<STRONG>verify_cb</STRONG> overwriting any existing callback.

</P>
<P>
<CODE>X509_STORE_set_verify_cb_func()</CODE> also sets the verification
callback but it is implemented as a macro.

</P>
<P>

<H1><A NAME="NOTES">NOTES</A></H1>
<P>
The verification callback from an <STRONG>X509_STORE</STRONG> is inherited by the corresponding <STRONG>X509_STORE_CTX</STRONG> structure when it is initialized. This can be used to set the verification
callback when the <STRONG>X509_STORE_CTX</STRONG> is otherwise inaccessible (for example during S/MIME verification).
