=head1 DESCRIPTION
The following B<flags> are currently recognized:
-B<CONF_MFLAGS_IGNORE_ERRORS> if set errors returned by individual
+If B<CONF_MFLAGS_IGNORE_ERRORS> is set errors returned by individual
configuration modules are ignored. If not set the first module error is
considered fatal and no further modules are loaded.
Normally any modules errors will add error information to the error queue. If
B<CONF_MFLAGS_SILENT> is set no error information is added.
+If B<CONF_MFLAGS_IGNORE_RETURN_CODES> is set the function unconditionally
+returns success.
+This is used by default in L<OPENSSL_init_crypto(3)> to ignore any errors in
+the default system-wide configuration file, as having all OpenSSL applications
+fail to start when there are potentially minor issues in the file is too risky.
+Applications calling B<CONF_modules_load_file> explicitly should not generally
+set this flag.
+
If B<CONF_MFLAGS_NO_DSO> is set configuration module loading from DSOs is
disabled.
configuration file themselves and have finer control over how errors are
