/****************************************************************************
Create an error packet. Normally called using the ERROR() macro.
- Setting eclass and ecode only and status to NT_STATUS_OK forces DOS errors.
- Setting status only and eclass and ecode to zero forces NT errors.
- If the override errors are set they take precedence over any passed in values.
+
+ Setting eclass and ecode to zero and status to a valid NT error will
+ reply with an NT error if the client supports CAP_STATUS32, otherwise
+ it maps to and returns a DOS error if the client doesn't support CAP_STATUS32.
+ This is the normal mode of calling this function via reply_nterror(req, status).
+
+ Setting eclass and ecode to non-zero and status to NT_STATUS_OK (0) will map
+ from a DOS error to an NT error and reply with an NT error if the client
+ supports CAP_STATUS32, otherwise it replies with the given DOS error.
+ This mode is currently not used in the server.
+
+ Setting both eclass, ecode and status to non-zero values allows a non-default
+ mapping from NT error codes to DOS error codes, and will return one or the
+ other depending on the client supporting CAP_STATUS32 or not. This is the
+ path taken by calling reply_botherror(req, eclass, ecode, status);
+
+ Setting status to NT_STATUS_DOS(eclass, ecode) forces DOS errors even if the
+ client supports CAP_STATUS32. This is the path taken to force a DOS error
+ reply by calling reply_force_doserror(req, eclass, ecode).
+
+ Setting status only and eclass to -1 forces NT errors even if the client
+ doesn't support CAP_STATUS32. This mode is currently never used in the
+ server.
