 SSL_CTX_set1_param() and SSL_set1_param() set the verification parameters
 to B<vpm> for B<ctx> or B<ssl>.
 
+The functions SSL_CTX_set_purpose() and SSL_set_purpose() are shorthands which
+set the purpose parameter on the verification parameters object. These functions
+are equivalent to calling X509_VERIFY_PARAM_set_purpose() directly.

+The functions SSL_CTX_set_trust() and SSL_set_trust() are similarly shorthands
+which set the trust parameter on the verification parameters object. These
+functions are equivalent to calling X509_VERIFY_PARAM_set_trust() directly.
