The most important thing is to keep the internal instance of the database
|
|
up to date. You can watch database changes with the <code>cl_stat</code>
|
|
functions family:
|
|
<PRE>
|
|
int cl_statinidir(const char *dirname, struct cl_stat *dbstat);
|
|
int cl_statchkdir(const struct cl_stat *dbstat);
|
|
int cl_statfree(struct cl_stat *dbstat);
|
|
</PRE>
|
|
Initialization:
|
|
<PRE>
|
|
struct cl_stat dbstat;
|
|
|
|
memset(&dbstat, 0, sizeof(struct cl_stat));
|
|
cl_statinidir(dbdir, &dbstat);
|
|
</PRE>
|
|
To check for a change you only need to call <code>cl_statchkdir</code>:
|
|
<PRE>
|
|
if(cl_statchkdir(&dbstat) == 1) {
|
|
reload_database...;
|
|
cl_statfree(&dbstat);
|
|
cl_statinidir(cl_retdbdir(), &dbstat);
|
|
}
|
|
</PRE>
|
|
Remember to reinitialize the structure after a reload.
