Re: [TCLUG:3621] Logfile?

I think you should use the  syslog functions in  /usr/include/syslog.h
instead of the re-direction. 

I am not sure if the ">>" maintains a lock/unlock so if there are 2
programs doing a ">>" how the output would appear to be. 

Take a look at "man 3 syslog" for more information. For a script
you can use the "logger" command. The man page should contain
more information.

By using the syslog functions you can avoid a dependancy on 
the location of the log file.

Hope this helps.
