The following code which I put at the beginning of getxover() seems to
work quite neatly at the moment:
if ( lastgroup && strcmp( groupname, lastgroup ) == 0 ) {
/* repeated XOVER requests for the same group */
time_t mtime_dir;
/* if the last access time of the .overview file is newer than
* that of the directory, the .overview file is up to date which
* also means that the overview data in memory are up to date.
*/
if ( !stat( ".", &st ) ) {
mtime_dir = st.st_mtime;
if ( !stat(".overview", &st) && (st.st_atime > mtime_dir) ) {
return 1;
}
}
}
Or did I overlook something?
