   the actual buffering. In particular these are:
   readdir() -> cReadDir
   readline() -> cReadLine
-  strescape() -> cStrEscape
-  AddDirectory() -> cAddDirectory
-  ctime() -> cCtime
-  itoa() -> cItoa
-  WeekDayName() -> cWeekDayName

+- Several formerly non-threadsafe functions now have a return type of cString:
+  cChannel::ToText()
+  tChannelID::ToString()
+  cEvent::GetDateString()
+  cEvent::GetTimeString()
+  cEvent::GetEndTimeString()
+  cEvent::GetVpsString()
+  cMark::ToText()
+  cTimer::ToText()
+  cSource::ToString()
+  cTimer::PrintDay()
+  cTimer::PrintFirstDay()
+  PrefixVideoFileName()
+  IndexToHMSF()
+  ChannelString()
+  strescape()
+  AddDirectory()
+  itoa()
+  WeekDayName()
+  DayDateTime()
+  When using these functions in a 'const char *' context there is nothing special
+  to consider, except that you can no longer have a pointer to the return value,
+  as in
+  const char *date = DayDateTime();
+  Although this will compile without error message, the resulting 'date' will not
+  be valid after this line. Use this instead:
+  cString date = DayDateTime();
+  In a 'const void *' context (as in printf() etc.) the result needs to be
+  dereferenced with a '*', as in
+  printf("%s", *DayDateTime());
+  to make it a 'const char *'.
 - Removed delay_ms(), using cCondWait::SleepMs() instead.
 - Replaced time_ms() with a threadsafe and non-overflowing cTimeMs (thanks to Rainer
   Zocholl for pointing out this problem).
