[vdr] thread proof/reentrance

[Rainer Zocholl <UseNet-Posting-Nospam-74308-@zocki.toppoint.de>]

While digging in the code:

msi:~/video/VDR# grep ctime *.c | grep -v ctime_r
eit.c:     isyslog("System Time = %s (%ld)\n", ctime(&loctim), loctim);
eit.c:     isyslog("Local Time  = %s (%ld)\n", ctime(&sattim), sattim);
svdrp.c:        char *s = ctime(&Start);
svdrp.c:        Reply(220, "%s SVDRP VideoDiskRecorder %s; %s", buffer, VDRVERSION, ctime(&now));
vdr.c:                       dsyslog("next timer event at %s", ctime(&Next));


Is is ok not to use the reenttrant ctime_r in a multi threaded environment?

eit.c uses a mutex
But: what does this help as svdrp.c and vdr.c seems not to use a mutex
(and: does the mutex really globally lock the access to all clib calls?)
or someone forgot to ask for the clib-mutex (if there is such a mutex)?)

May that never cause "funny" time results?

(Mostly it does not matter, as all threads are having the same time, 
but sometimes?)
