Field Documentation

gboolean(* QofBackend_s::save_may_clobber_data)(QofBackend *)

Detect if the sync operation will overwrite data

File based backends tend to consider the original file as 'stale' immediately the data finishes loading. New data only exists in memory and the data in the file is completely replaced when qof_session_save is called. e.g. this routine can be used to detect if a Save As... operation would overwrite a possibly unrelated file. Not all file backends use this function.

Returns:
TRUE if the user may need to be warned about possible data loss, otherwise FALSE.

QofErrorId QofBackend_s::last_err

Deprecated:
use qof_error_check instead.

gchar* QofBackend_s::error_msg

Deprecated:
use stack instead.

Definition at line 326 of file qofbackend-p.h.

gchar* QofBackend_s::fullpath

Each backend resolves a fully-qualified file path. This holds the filepath and communicates it to the frontends.
