C++ Sockets

C++ Sockets is a cross-platform, easy-to-use and completely free library software implemented in C++ and designed to be used as a wrapper for creating BSD-style sockets in open source applications.

Supports SSL, IPv6, UDP, TCP and HTTP protocols

The library provides support for SSL (Secure Sockets Layer), IPv6, TCP (Transmission Control Protocol), UDP (User Datagram Protocol), encrypted TCP, HTTP, as well as highly customizable error handling.

C++ Sockets implements the SCTP (Stream Control Transmission Protocol), UDP, TCP, and ICMP (Internet Control Message Protocol) transport layer protocols, as well as the HTTP/HTTPS, SMTP and Ajp/1.3 application layer protocols.

Getting started with C++ Sockets

To install and use the C++ Sockets software on your GNU/Linux operating system, you must download the latest version from Softoware or directly from the project’s official website, where it is distributed as a source archive.

Save the archive somewhere on your PC, extract its contents using an archive manager utility, open a terminal emulator application and move to the location of the extracted archive files using the ‘cd’ command (e.g. cd /home/softoware/Sockets-2.3.9.9).

Run the ‘make’ command (without quotes) to compile the library, making sure that a GCC compiler is installed on your GNU/Linux operating systems. After a successful compilation, run the ‘make install’ command as root or the ‘sudo make install’ command as a privileged user to install C++ Sockets system wide. Run the ‘Sockets-config’ command to see how you can interact with the library.

Under the hood

Taking a look under the hood of the C++ Sockets library software, we can notice that it has been written entirely in the C++ programming language and designed to support GNU/Linux, Solaris, Microsoft Windows and Mac OS X operating systems. It works on 64-bit and 32-bit computers.

What is new in this release:

• A bug that prevented HttpGetSocket from exiting normally if a zero byte resource was fetched was fixed.
• Some missing includes were included for newer compilers.

What is new in version 2.3.9.7:

• Detach threads that never stopped has been fixed.
• Detaching from OnAccept method now works.
• Time to launch a detached thread has been reduced.

What is new in version 2.3.9.6:

• A timing problem has been solved in detached sockets.
• More configure options have been added.
• Lost state flags are now retrieved in sockethandler.
• The AJP client socket has been updated.
• The JSON parser has been updated.

What is new in version 2.3.9.3:

• Multithread support was added in sockethandler.
• Build problems in mingw/cygwin were fixed.

What is new in version 2.3.9.2:

• More internal restructuring of SocketHandler.
• The Get() method has been removed. Set() has been split into three:
• ISocketHandler_Add(), ISocketHandler_Mod(), and ISocketHandler_Del().
• New methods defined in ISocketHandler interface to support different
• models of socket io: ISocketHandler_Select(), MaxCount().
• Removed Set() method from Socket class.
• Implemented SocketHandlerEp using epoll for linux only.
• reinterpret_cast added in ListenSocket for ipv6 address struct.
• HttpPostSocket member variable holding http headers (m_fields) is now
• protected (changed from private).
• Repaired Reconnect function in sockethandler.

What is new in version 2.3.9.1:

• Major restructure of sockethandler internal code. Using thread- and memorysafe clib/c runtime functions.

What is new in version 2.3.7:

• A hanging write call when using SSL was fixed.
• A crash when trying to increase an STL iterator beyond its limits was fixed.
• Compilation problems caused by missing #include statements or #include statements inside the library namespace were fixed.

What is new in version 2.3.6:

• The openssl flags were modified to make things flow smoother.
• The license was modified to allow openssl.
• A unique socket identifier and a new valid check were added.
• Filesystem path abstraction methods were added.
• A Changelog file was added to the distribution.
• The INSTALL was renamed to README.
• The pkgconfig directory and *.pc definition file were added.

What is new in version 2.3.5:

• Added method(s) in UdpSocket to set default interface to be used for multicast.
• Added flag for position independent code for linux-x86-32 architecture (see
• Makefile.Defines.linux-x86-32).
• Added missing includes (on some distributions/gcc versions).
• SetUri in HttpRequest no longer URLDecodes the entire url.
• Fix for static variables in SSLInitializer.
• Fix for new version of openssl (const SSLxx_method()).
• Fix for getnameinfo.
• Modified Utility::Uri parser class so it also splits the url in path /
• querystring parts.
