# writeFromSync method

void writeFromSync (List<int> buffer, [ int start = 0, int end ])

Writes data from a specified range in a List to the socket.

Writes into the socket from a List. If `start` is present, the bytes will be written to the socket starting from index `start`. If `start` is not present, the bytes will be written starting from index 0. If `end` is present, the `end` - `start` bytes will be written into the socket starting at index `start`. If `end` is not provided, `buffer.length` elements will be written to the socket starting from index `start`. If `end` == `start`, nothing happens.

## Implementation

    void writeFromSync(List<int> buffer, [int start = 0, int end]);
