Question

In my code i have to pass a bye array (byte[] temp = null;) to a
function which is allocated and filled with data inside it. After
returning from function it is still null. How can i find a
solution to this problem.??? Please help me.

  byte[] temp = null;
  ret = foo(temp);

  boolean foo(byte[] temp)
  {
      temp = new byte[];
      //fill array
  }

You need to use this:

 byte[] temp = new byte[some_const];
  ret = foo(temp);

  boolean foo(byte[] temp)
  {
      //fill array
  }

or

 byte[] temp = null;
  temp  = foo(temp);

  byte[] foo(byte[] temp)
  {    temp = new byte[some_const];
      //fill array
      return temp;
  }
