Re: Perl 5, version 14, subversion 2 (v5.14.2)
Cygwin: CYGWIN_NT-5.1 1.7.25(0.270/5/3
In Perl (I am attempting to open a file and put an exclusive lock on it to update
it like this:
###########################################
use Fcntl qw( O_RDWR O_CREAT O_NONBLOCK O_EXLOCK );
sysopen($FH, $fname, O_RDWR | O_CREAT | O_NONBLOCK | O_EXLOCK, 0664)
############################################
Result on a test run give me the following error message:
"Your vendor has not defined Fcntl macro O_EXLOCK,"
Is it possible to develope perl code on cygwin that can use file locking to update data in a file from within perl?
Thank you.
