librapi2 (SynCE library) The RAPI library is an open source implementation that works like RAPI.DLL, available on Microsoft operating systems. The library makes it possible to make remote calls to a computer running device. Documentation for the RAPI calls is available at this address: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wcesdkr/htm/_wcesdk_CeRapiInit.asp In order to use librapi, a daemon that the device client connects to must be running on the computer using librapi.
