 aliases, so that multiple NID's can map to the same domain parameters. For such curves it is unspecified which of the aliases will be
 returned if the curve name of the given group is NID_undef.
 If B<nist_only> is 1 it will only look for NIST approved curves, otherwise it searches all built-in curves.
+This function may be passed a BN_CTX object in the B<ctx> parameter.

 EC_GROUP_cmp compares B<a> and B<b> to determine whether they represent the same curve or not.
