How to develop an application like a nispy application?

[kimhoesoo]

Currently, I use GPIB card of national instrument, and I hope to utilize some functions in NiSpy application.

However, I don't have NiSpy source, so I try to develop an application like NiSpy. 

Is there anyone who has the source of smiliar application to NiSpy?

Please, help me >.<

I'm  not sure why you want to do this.

NIspy does have a LabVIEW API (and presumablly a LabWindows/CVI interface) For Windows only.  What OS and Language are you trying to re-invent the wheel in?

[kimhoesoo]

OS : Windows / Linux / Unix / SunOS

Language : Ansi-C

I need the API developed with C, Could you attach the source on this web-site?

I certainly cannot attach NI-source code. If I had access to it it would most certainly be under a NDA- I don't even work for NI.  Digging into the LabVIEW API all the functions are a very shallow hierarchy calling into the NiSpyLog.dll through Call Library function configured with a WINAPI convention and only a windows target is enabled.

You may need to "roll your own" to get cross platform performance.
