+        int argc, char* argv[] )</codeph>. On Symbian platform, programs are invoked through an <codeph>E32Main()</codeph> function taking no arguments. Most Symbian programs are launched through a graphical shell rather than through a command-line. The common exceptions are <filepath>.exe</filepath> s on the PC platform, which can be run from a Windows command prompt. </p> <p>For <filepath>.exe</filepath> programs, control is received through the <codeph>E32Main()</codeph> function, which does not supply arguments. Instead, access to arguments is provided by <xref href="GUID-CE114EA5-A084-39A5-9F48-14344AB5BDBA.dita"><apiname>CCommandLineArguments</apiname></xref>. This class is not intended primarily for code running on a Symbian phone. Its main use is in parsing the arguments of WINC command-line utilities. </p> <p>For a program that is launched as a new process, the arguments are available as part of the process command line and may be obtained in full using code as the following: </p> <codeblock id="GUID-CA0EBC3E-1FB5-5E39-8790-DE3131DB1B77" xml:space="preserve">TInt argLen = User::CommandLineLength();
+HBufC16* hBuf = HBufC::NewL( argLen );
+TPtr tPtr = hBuf-&gt;Des();
+User::CommandLine( tPtr );</codeblock> <p>However, the arguments are in a raw form. For convenience, the <codeph>CCommandLineArguments</codeph> class provides functions to access the program name as argument 0, and each command-line argument as argument 1, 2 etc. Arguments beginning with a quote may contain blanks and doubled quotes. Arguments not beginning with a quote are terminated by a blank. </p> </conbody></concept>
