This function returns <=0 on error, not only 0. This is evident by looking at the implementation where it can return a negative error here [1]. Use in OpenSSL itself also uses the <=0 check [2].

This was found by a hybrid static-dynamic analyser that looks for inconsistent handling of error checks in bindings.
