Hi, Iam new to Libsvm.iam using Libsvm and i have added svm.cpp and svm.h files to my project. i have my model files stored in the project folder and the scale file which use to do the prediction.My problem is what is the method i should use to do the prediction in svm.cpp?

For the prediction part if i use svmprediction.exe file which is inside the libsvm package, i have to give,
1. Test.scale file path (which has my test values)
2. X.scale.model file path
3. Output file (which stores the result of the prediction)

But now i want to do it using svm.cpp.I can't find any type of method which accepts above 3 parameters.Need help.Thank you..I hope my problem is clear :-)
