Hi all,
I have an Producer/Consumer program in C(using shared memory and semaphores).It is working fine with sleep calls after every read/write operation.Each one is a independent program.Now if i remove the sleep calls in consumer,it goes on waiting in the loop till the producer puts some valid...

The intention of the program. Create N threads with 2 shared memories.
One shared memory to write, one shared memory to recieve.
Consumer creates 2 shared memory to share with producer.
I need H threads for the producer as well(somebody help on it..)
Also another question, would segment_id... (2 Replies)
I would like to loop through a set of directories, performing operation(s) on each one. The basic script** is
dirs=`find . -name .svn -print`
for f in $dirs; do
echo "Processing $f directory .."
done
Fine and dandy, but here is the problem: the find expression must complete... (7 Replies)
Control two exclusively shared resources. The two resources are two files. The producer will write even numbers to one file, and odd numbers to another one. The consumer respectively reads from each file until it gets 5 even numbers and 5 odd numbers.
Can any one help me with the code.

Git::SVN::Fetcher(3) User Contributed Perl Documentation Git::SVN::Fetcher(3)NAME
Git::SVN::Fetcher - tree delta consumer for "git svn fetch"
SYNOPSIS
use SVN::Core;
use SVN::Ra;
use Git::SVN;
use Git::SVN::Fetcher;
use Git;
my $gs = Git::SVN->find_by_url($url);
my $ra = SVN::Ra->new(url => $url);
my $editor = Git::SVN::Fetcher->new($gs);
my $reporter = $ra->do_update($SVN::Core::INVALID_REVNUM, '',
1, $editor);
$reporter->set_path('', $old_rev, 0);
$reporter->finish_report;
my $tree = $gs->tmp_index_do(sub { command_oneline('write-tree') });
foreach my $path (keys %{$editor->{dir_prop}) {
my $props = $editor->{dir_prop}{$path};
foreach my $prop (keys %$props) {
print "property $prop at $path changed to $props->{$prop}
";
}
}
foreach my $path (keys %{$editor->{empty}) {
my $action = $editor->{empty}{$path} ? 'added' : 'removed';
print "empty directory $path $action
";
}
foreach my $path (keys %{$editor->{file_prop}) { ... }
foreach my $parent (keys %{$editor->{absent_dir}}) {
my @children = @{$editor->{abstent_dir}{$parent}};
print "cannot fetch directory $parent/$_: not authorized?
"
foreach @children;
}
foreach my $parent (keys %{$editor->{absent_file}) { ... }
DESCRIPTION
This is a subclass of "SVN::Delta::Editor", which means it implements callbacks to act as a consumer of Subversion tree deltas. This
particular implementation of those callbacks is meant to store information about the resulting content which git svn fetch could use to
populate new commits and new entries for unhandled.log. More specifically:
o Additions, removals, and modifications of files are propagated to git-svn's index file $GIT_DIR/svn/$refname/index using git update-
index.
o Changes in Subversion path properties are recorded in the "dir_prop" and "file_prop" fields (which are hashes).
o Addition and removal of empty directories are indicated by entries with value 1 and 0 respectively in the "empty" hash.
o Paths that are present but cannot be conveyed (presumably due to permissions) are recorded in the "absent_file" and "absent_dirs"
hashes. For each key, the corresponding value is a list of paths under that directory that were present but could not be conveyed.
The interface is unstable. Do not use this module unless you are developing git-svn.
DEPENDENCIES
SVN::Delta from the Subversion perl bindings, the core Carp, File::Basename, and IO::File modules, and git's Git helper module.
"Git::SVN::Fetcher" has not been tested using callers other than git-svn itself.
