Ein Graus - File lock

[Günter Laudenklos]

Hallo Michel,

warum nicht so ?

open (FILE,"+<$file") or die # open file
flock(FILE,2);     # lock file exclusive
seek (FILE,0,0);    # position at start

@records = <LOGFILE>;

... weitere Verarbeitung

seek (FILE,0,0);    # position at start
print (FILE @newrecs);
truncate (LOGFILE,tell(LOGFILE));

flock(FILE,8);     # release lock
close(FILE);

und in anderen cgis, die nur lesen:

open (FILE,"$file") or die # open file
flock(FILE,1);    # lock file shared

... weitere Verarbeitung

viele Grüße Günter
