Effectively the values in "to" become default values - * which will be used only if nothing new is set in "from". - * - * If X509_VP_FLAG_OVERWRITE is set then all value are copied across whether - * they are set or not. Flags is still Ored though. - * - * If X509_VP_FLAG_RESET_FLAGS is set then the flags value is copied instead - * of ORed. - * - * If X509_VP_FLAG_LOCKED is set then no values are copied. - * - * If X509_VP_FLAG_ONCE is set then the current inh_flags setting is zeroed - * after the next call. - */ - -/* Macro to test if a field should be copied from src to dest */ - -#define test_x509_verify_param_copy(field, def) \ - (to_overwrite || \ - ((src->field != def) && (to_default || (dest->field == def)))) - -/* As above but for ID fields */ - -#define test_x509_verify_param_copy_id(idf, def) \ - test_x509_verify_param_copy(id->idf, def) - -/* Macro to test and copy a field if necessary */ - -#define x509_verify_param_copy(field, def) \ - if (test_x509_verify_param_copy(field, def)) \ - dest->field = src->field - -int X509_VERIFY_PARAM_inherit(X509_VERIFY_PARAM *dest, - const X509_VERIFY_PARAM *src) -{ - unsigned long inh_flags;
