How to get command line parameters in c++?

I’m using UE 4.10. I need to parse command line parameters in c++ when the program start.

Where can I get the argc, argv? Where should I put the c++ code for parsing command line parameters?

Thanks really.

I’ll answer it myself, if any one need to know:

FCommandLine::Get();

If anyone wants to know how to parse arguments from FCommandLine::Get():

FString ParameterValue;
if (FParse::Value(FCommandLine::Get(), TEXT("ParameterName"), ParameterValue)) 
{
    // The parameter "ParameterName" has been set and ParameterValue contains its value
}

Includes:

#include "Misc/Parse.h"       // FParse
#include "Misc/CommandLine.h" // FCommandLine
