Database reloading</A>
</H2>
It's very important to keep the internal instance of the database up to
date. You can watch database changes with the <code>cl_stat..()</code> family
of functions.
<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 just need to call <code>cl_statchkdir</code> and check
its return value (0 - no change, 1 - some change occured): |

<PRE> |

if(cl_statchkdir(&dbstat) == 1) {
reload_database...;
cl_statfree(&dbstat);
cl_statinidir(cl_retdbdir(), &dbstat);
} |
f7f59c08 |
</PRE> |

Remember to reset the <code>cl_stat</code> structure after each reload. |
