Например https://github.com/freedesktop/fontconfig/blob/master/src/fc... FcBool FcInitBringUptoDate (void) {     FcConfig    *config = FcConfigReference (NULL);     FcBool    ret = FcTrue;     time_t    now;     if (!config)     return FcFalse;     /*      * rescanInterval == 0 disables automatic up to date      */     if (config->rescanInterval == 0)     goto bail;     /*      * Check no more often than rescanInterval seconds      */     now = time (0);     if (config->rescanTime + config->rescanInterval - now > 0)     goto bail;     /*      * If up to date, don't reload configuration      */     if (FcConfigUptoDate (0))     goto bail;     ret = FcInitReinitialize (); bail:     FcConfigDestroy (config);     return ret; } https://github.com/freedesktop/fontconfig/blob/master/fc-cac...   /*      * Now we need to sleep a second  (or two, to be extra sure), to make      * sure that timestamps for changes after this run of fc-cache are later      * then any timestamps we wrote.  We don't use gettimeofday() because      * sleep(3) can't be interrupted by a signal here -- this isn't in the      * library, and there aren't any signals flying around here.      */     /* the resolution of mtime on FAT is 2 seconds */ Надеюсь сам догонишь, для чего кэшу время?
