how to access UNICODE_STRING CommandLine variable?

I found out that the command line arguments for a program run in windows are stored in Process Environment block.I found out more that inside PEB there is a structure called RTL_USER_PROCESS_PARAMETERS , which holds a member variable named UNICODE_STRING CommandLine; can i access this variable by writing a c code ? please assist For more information about PEB refer this link http://msdn.microsoft.com/en-us/library/aa813706%28VS.85%29.aspx

You need the GetCommandLine function. Even if your program is ANSI, you can still explicitly call the wide version, GetCommandLineW.

This function is documented on MSDN. Look in the Requirements section and you'll see that it is defined in WinBase.h but that you should include Windows.h. It is only available starting with Windows XP, so depending on the version of the SDK that you're using you might need to define _WIN32_WINNT first:

#define _WIN32_WINNT 0x0502
#include <windows.h>
