If this is not homework - School work , why are you posting here?
If it is then please follow the rules: fill in the template you see here:
https://www.unix.com/homework-coursew...ons-forum.html
It is not your first post here so please understand:
This is VERY important since the forum has an agreement (with many Education...) to let students post here, but only at that condition...
So thread closed unless you say it is not homework in which case it has nothing to do here...

I will accept to open it here under the very condition of you stating which school etc.. and you are learning and wanting some help as student (very good, welcome!) and this is not or related to an assignment in which case you agree to open a new thread and comply to the requirements.

Shared memory in shared library

I need to create a shared library to access an in memory DB. The DB is not huge, but big enough to make it cumbersome to carry around in every single process using the shared library. Luckily, it is pretty static information, so I don't need to worry much about synchronizing the data between... (12 Replies)

Shared memory for shared library

I am writing a shared library in Linux (but compatible with other UNIXes) and I want to allow multiple instances to share a piece of memory -- 1 byte is enough. What's the "best" way to do this? I want to optimize for speed and portability. Obviously, I'll have to worry about mutual exclusion. (0 Replies)

NAME
Arch::LiteWeb - simple way to access web pages SYNOPSIS
my $web = Arch::LiteWeb->new; my $content = $web->get("http://some.domain:81/some/path"); die $web->error . " while processing " . $web->request_url unless $content; my $content_type = $web->response_headers->{content_type}; DESCRIPTION
This class provides a basic and easy to use support for the client-side HTTP. It is supplied in order to avoid dependency on LWP. If such dependency is not a problem, consider to use LWP instead that provides much better support for HTTP and other protocols. METHODS
The following class methods are available: get, post, request_url, error, error_with_url, network_error, response_code, response_codestr, response_error, response_headers, response_content. get url [params ...] Execute HTTP get of the given url and return the html string or undef on network/response error. Use other methods to get the details about the error and the response. params is key-value hash, the following keys are supported: url_host - only used if url is none url_port - only used if url is none(80) url_path - only used if url is none endl - default is "1512" timeout - default is 20 seconds user_agent - default is "Arch::LiteWeb/0.1" nocache - add a no-cache header noredirect - don't follow redirect responses max_redirect_depth - default is 5 use_proxy - default is false proxy_url - proxy url ($http_proxy supported too) proxy_host - only used if proxy_url is none proxy_port - only used if proxy_url is none(80) post url input [params] Not implemented yet. request_url Actual url of the last issued request or undef. If partial redirect responses are enabled, then the result is the last (non-redirect) url. error If the last request resulted in error (i.e. get/post returned undef), then this method returns the error message, otherwise it returns undef. This is just a shortcut for network_error || response_error. error_with_url Like error, but with " while fetching request_url " text appended if non undef. network_error The network error message for the last request or undef. response_error The response error message for the last request or undef. response_code The last response code (integer) or undef. response_codestr The last response code (string) or undef. response_headers The last response headers (hashref of HTTP headers) or undef. response_content The last response content or undef. This is the same thing that the last get/post returns. BUGS
