Database reloading</A>
</H2>
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.
