Sudheer,
I think you're on the right track. Keep in mind that you can set the slp.conf path on the configure command line - the path used by the libraries and services built is thus hard-coded into the applications and libraries. Set it to something closer to you, and to which you have more rights. Where you choose to locate your configuration file should be based on the way your OS stores and accesses such configuration files. I'm not familiar with the way iOS works, so I can't help you there, but as a developer, some of these things should already be clear to you.

As you mentioned, I've tested with slptool on Mac OS X, Leopard as well as on Snow Leopard. We already have an app which is using SLP and ACN, so I've tested the slptool that is present in that particular application and came to know that the tool is looking for slp.conf file in a particular location(/usr/local/etc/slp.conf). When we tested on Leopard using slptool, we got all the devices in the network, but when we tested on SnowLeopard using slptool, initially we didn't get any devices. Later found that the slp.conf file in /usr/loca/etc/ is missing. So, placed that file in that particular location and then we are able to see all the devices using slptool in Mac OS. I think that the same issue exists in iOS as well as we are not using the slp.conf file. Please find the attached output after compiling OpenSLP for iOS. We are just using the slp.h include file and the libslp.a static library from that output in our iOS application. Since we cannot place the slp.conf file to root directory as iPhone is Sand Boxed, we must have some way to either set the configuration in the code itself or set the path of the slp.conf file explicitly so that we can have the slp.conf file in our project and set the path to that specific file? Please let us know if we are going in a wrong way anywhere. NOTE: we are working on openslp-1.2.1 version. Getting errors while compiling openslp-2.0.beta2 .

Don't give up - openslp is used pervasively - even by hardware vendors - so it's not a problem with the spec or the library, unless it's a porting issue. It's probably something as simple as not looking for the same thing you're advertising, which can happen when you misformat your query string.

Some would probably be close, others would be nowhere near the problem. In this situation, especially where you've ported the library to a new platform, it's probably going to do you much more good to simply debug your application - step into the client library and see where your failure is coming from. If you find an exact function that's causing an error to be returned, post that information. If you're not getting an error, but simply an empty list of results, then you should form the same request with slptool (on a tested platform like windows or linux - or even the mac) to determine if you're forming your request properly.

Now, we have created a sample iOS application with the code mentioned in the link ( http://openslp.org/doc/html/ProgrammersGuide/SLPFindSrvs.html ) to find the devices in the network. The call back is getting called but with an error code as errcode == SLP_LAST_CALL and thus resulting in the following log. Service URL = (null) Service Timeout = 0 There are two devices in the network with the service which I'm looking for but I'm not getting those devices when I use the code mentioned in the above link. Can someone help me out as what could be the problem. Please find the code snippet as attached.

Thanks to the efforts of one of our team members, Alan Adams, we have some very clean documentation. Start with the OpenSLP Programmer's Guide (http://openslp.org/doc/html/ProgrammersGuide/index.html). Look particularly at the service location functions in the bottom left corner. These three functions are at the heart of every User Agent (UA) application. Click on a function - SLPFindSrvs, for instance - they have great docs, and example code at the bottom of the page. In short, include slp.h in your code to prototype the functions and give your code access to the requisite OpenSLP data structures. Follow the example code you find in the programmer's guide.

Now I just want to know how to use it with out using SLPD. Since there is no option to run separate processes in iOS, we can't run SLPD in iOS. I just want to have a User Agent functionality for my iOS app which actually discovers all the devices with a specific service in the network. Can anyone help me out as how to proceed further (which functions to use) in discovering the devices without using SLPD. Thanks Sudheer 2011/7/27 Varun Chandramohan <var...@linux.vnet.ibm.com> Hi Sudheer, I think better option would be for you to use the latest source. openslp-2.0-beat2. Iam not an expert in ipad/iphone development, but i know that one of the developers here have atleast tested it on mac os!
