CSVtoStr

Extract a single parameter from a CSV formatted string.

Description#

CSVtoStr( const data[], destination[], maxlen, item )

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#

   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.
