Hi, everyone, When I used the flock(f,s) in Unicon,
flock(str_filename,”x”) is OK,
but flock(str_filename,”u”) is not
available, the &errortext returned is ------------------------------------------------ Run-time error
1044 File try.icn; Line
17 invalid operation to
flock/fcntl offending value:
"u" Traceback:
main() flock(file(try.icn),"u")
from line ----------------------------------------------- What is wrong when using flock(f,s)
? My trial code is followed
: ~~~~~~~~~~~~~~~~~~~~~~~ procedure
main() str :=
"try.icn" p:= open(str,"b") |
stop(&errortext) flock(p,"x") write("lock file
...") while l := read(p) do
write(l) write(p,"\n\n add
info.") ; delay(1000*40) flock(p,"u") write("unlocked ... ");
delay(1000*60*2) close(p) end ~~~~~~~~~~~~~~~~~~~~~~~~~ |
