==== CSVtoStr ====

Extract a single parameter from a CSV formatted string.

=== Description ===

<code>CSVtoStr( const data[], destination[], maxlen, item )</code>

Extract single parameter from a CSV formatted string.

=== Parameters ===

| ''data'' | CSV formatted string |
| ''destination'' | Buffer for extracted parameter |
| ''maxlen'' | Max size of the destination buffer |
| ''item'' | Which item to extract. The first item is 1. |

Assuming the input data is properly formatted as a CSV string (comma separated), this command finds the item by count and copies the string data into destination.

=== Return value ===

Number of characters copied into destination. If the item is not found, return 0.

=== Example usage ===

<code javascript>    
   new param{128};
   new csvdata{} = "123, 1234, \"some string\", \"more data\"";

   CSVtoStr( csvdata, param, 128, 3 ); 
   
   // param will now hold the text "some string" without quotes.
