Hi i am trying this code

{

		unsigned char *data,*test;
		unsigned char ch;
		JsVar *str = jsvAsString(var, false);	
		data=test;
		JsvStringIterator it;
		jsvStringIteratorNew(&it, str, 0);	 
		while (jsvStringIteratorHasChar(&it)) 
		{
			ch = (unsigned char)jsvStringIteratorGetChar(&it);
			jsiConsolePrintf("\r\n ch: %c",ch);
			*test++=ch;
			jsvStringIteratorNext(&it);
	    }
	    jsvStringIteratorFree(&it);
	    jsvUnLock(str);
}

but it is not working...
any suggestions please...

Thanks
Vishnu

You're not initialising 'test' to anything and you're not zero terminating the string...

I think jsvGetString does exactly what you want though?

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

> Quote text by starting lines with >

For syntax highlighting, surround the code block with three backticks:

```
Your code goes here
```
Just like Github, a blank line must precede a code block.

If you upload more than 5 files we will display all attachments as thumbnails.
