HS MSG C/C++ Messaging Library

Instant messaging is an integral part of functionalities of computer networks today. It started some decades back with the enhancement in network capabilities and was done through computers and mainframes but has come up on a large scale to mobiles and various other portable devices. The market strength for a messaging application is very high provided it is comprehensive in features and functionality. If you are a developer and want to create a messaging application for a device or want to integrate instant messaging capabilities in your applications, then you must certainly try using HS MSG C/C++ Messaging Library v.1.0.0.

HS MSG C/C++ Messaging Library by HillStone Software is a shareware program which acts as a middleware in messaging network for communication among threads pertaining to same process and among different processes on the same thread. This software development kit has been designed to run on Mac OSX, iPhone, Linux and Windows. The program has the most simplified interface in C for sending and receiving messages and receives messages asynchronously via a poll method using the HsMsgPollQueue() API. Similarly, the message sending can be either synchronous or asynchronous with respective APIs. The messages containing large data set can also be sent using this program with data buffers in which re-assembly, segmentation and re-transmissions are handled by IP. It has a vast C library which is cross platform entailing Mac OSX, iOS, Unix, Linux and Windows. The program has the capability to handle multiple concurrent sessions of messaging and supports simultaneous sending and reception of messages.

Overall, HS MSG C/C++ Messaging Library v.1.0.0 is a nice application for creating standalone messaging applications or for embedding messaging capabilities in an application of any of the above platforms, leading it to score three and a half rating points on the scale of five.
