I know this is the MacPerl list, but I have an anyperl question.
I have a script like so:
#!/usr/bin/perl -w
use strict;
open(OUTPUT, ">out");
my $count = 0;
while ( 1 )
{
print "$count\n";
print OUTPUT "$count\n";
$count++;
}
# we terminate before we ever get here
close(OUTPUT);
While it is looping, I hit command-. in MacPerl to nuke it. While it
runs data is flushed to the terminal window, and the same data ends up
flushed to the file after the script is nuked even though I didn't
explicitly auto-flush the file handle.
Problem #1:
Take that same script and run it on a unix machine. Run it from the
terminal. Hit control-c while it is executing. Notice that all the
data isn't flushed to the output file.
Problem #2:
Run this same script by exec'ing it from another c program. Kill the
subprocess at some point that you know it is executing the loop. Notice
that all of the data isn't flushed to the output file, and that you
don't get all of the data back on your stdout pipe.
Is there any way to avoid this?
In particular, I want to nuke a program in mid-execution and have perl
clean up as best as it can at this point, which includes flushing the
buffers of any open files.
Thanks,
Jim
