Hi Klaus,

thanks for your answer. Tonight I tried to put some debugging output
into your code to narrow down the problem.

I put in to isyslog-messages around the function RemoveFileOrDir in
tools.c. As you can see the timepoint of entry to this function is to
the second the same as the point of return. This matches the results of
my tests on filesystem level - removal of a recording happens within a
second (Zeitpunkt Start vs. Zeitpunkt Ende). Please forgive the typos.

This is what appears in /var/log/messages:

--------------------------------------------------------------------

So, the problem I have is introduced somewhere beyond this function.

Some questions:

Is this the function where the actual removal of recordings happens?

What follows, processwise?

How does the concept of your watchdog work?

Thanks in advance and sorry for keeping you busy,

Benjamin


Here is what I put in your code:

>bool RemoveFileOrDir(const char *FileName, bool >FollowSymlinks)
>{
>  struct stat st;
>
  long int my_time;
  time(&my_time); 
  char my_buffer[100];
  sprintf(my_buffer, "Zeitpunktistart %ld", my_time); 
  isyslog("RemoveFileOrDir (tools.c) removing %s", my_buffer);

>  
  time(&my_time); 
  sprintf(my_buffer, "Zeitpunkti Ende %ld", my_time); 
  isyslog("RemoveFileOrDir (tools.c) removing %s", my_buffer);
>
