Using the ICQ API ICQ API is a set of functions implemented in a DLL. The API enables the query of data from the ICQ Client,initiating operations in the client and getting notifications from the client asynchronously.ICQ API FILESICQMsgAPI.lib - The ICQAPI library file.ICQMsgAPI.dll - The ICQAPI dll itself.ICQAPINotifications.h - the ICQAPI main header file.
