// Revision 1.15 2005/11/03 21:08:52 mogway
// sectionsd update by Houdini
//
// Changes:
// - EIT und SDT DMX buffer verändert
// -> keine(weniger) POLLER, kostet Speicher beim EITDMX, spart Speicher beim SDTDMX
//
// - vor dem Parsen der Sections werden die Buffer nicht mehr (unnötig) ein zweites mal allokiert und umkopiert -> mehr Performance, weniger Speicherfragmentierung
//
// - unnötige/unbenutze Funktionen auskommentiert -> das gestrippte sectionsd binary wird 23kB kleiner, Test-/Beispielprogramme wie sdt, epg, nit, ... können dann nicht mehr kompiliert werden.
//
// Revision 1.14 2003/03/03 13:38:33 obi
// - cleaned up changeUTCtoCtime a bit
// - finish pthreads using pthread_exit(NULL) instead of return 0
// - use settimeofday() instead of stime()
//
// Revision 1.13 2002/11/03 22:26:54 thegoodguy
// Use more frequently types defined in zapittypes.h(not complete), fix some warnings, some code cleanup
//
// Revision 1.12 2001/07/17 14:15:52 fnbrd
// Kleine Aenderung damit auch static geht.
//
// Revision 1.11 2001/07/14 16:38:46 fnbrd
// Mit workaround fuer defektes mktime der glibc
//
// Revision 1.10 2001/07/12 22:55:51 fnbrd
// Fehler behoben
//
// Revision 1.9 2001/07/12 22:51:25 fnbrd
// Time-Thread im sectionsd (noch disabled, da prob mit mktime)
//
// Revision 1.8 2001/07/06 11:09:56 fnbrd
// Noch ne Kleinigkeit gefixt.
//
// Revision 1.7 2001/07/06 09:46:01 fnbrd

// Jetzt wellformed xml.
//
// Revision 1.3 2001/05/18 13:11:46 fnbrd
// Fast komplett, fehlt nur noch die Auswertung der time-shifted events
// (Startzeit und Dauer der Cinedoms).
//
// Revision 1.2 2001/05/17 01:53:35 fnbrd
// Jetzt mit lokaler Zeit.
//
// Revision 1.1 2001/05/16 15:23:47 fnbrd
