.NET: rArg

An output parameter containing the value of the specified element. This parameter is null if the 
element is not found.

An Arg reference containing the value of the desired element.

The C++ and Java versions of this method return NULL if an error occurs, such as the key or element is 
not found. The .NET version of this method returns true upon success and false upon error.

The GetLastError method returns the last error that occurred on the calling thread.

Integer GetLastError()

System.Boolean GetLastError(out System.Int32 nLastError)

Java: None.

.NET: nLastError

Output parameter that is a 32-bit signed integer that contains the returned value of the last error.

Java:An Integer object containing the error, or null if the object is not found or if there is an error.

.NET:The Boolean value true if the value is successfully set; otherwise false.

The following example code gets the last error on the current thread and logs the error message. If 
GetLastError fails, the code writes a warning message to the log file.

// First get the last error System.Int32 myLastError; 

bool success = GetLastError(out myLastError); 

if (!success) 

{ 

// log a message indicating that GetLastError failed 

} 

else 

{ 

//log a message that indicates what the last error was 

LOGBYID(Cisco.CtiOs.Cil.TraceLevel.WARN, “GetLastError returned 

last error =” + myLastError); 

}
