Introductiontowsockexpert
TheMicrosoftWindowsSocketsAPIisasetoffunctionsanddatastructuresusedtocreatenetworkapplicationsonWindows-basedsystems.TheAPIisdesignedtobeusedbyCandC++developersandprovidesapowerfulsetoftoolsforcreatingnetworkapplications.Thewsockexpertlibraryisanopen-sourceimplementationoftheWindowsSocketsAPIthatprovidesadditionalfeaturesandfunctionalitynotfoundinthestandardimplementation.
Oneofthekeyfeaturesofwsockexpertisitssupportformultipleprotocols.ThelibraryprovidessupportforawiderangeofnetworkingprotocolsincludingTCP/IP,UDP,andHTTP.Thisallowsdeveloperstocreateapplicationsthatcancommunicatewithavarietyofnetworkedsystemsanddevices.
