# readIntoSync method

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

Reads into an existing List<int> from the socket into the range: [`start`,`end`).

Reads into an existing List<int> from the socket. If `start` is present, the bytes will be filled into `buffer` from index `start`, otherwise index

0. If `end` is present, `end` - `start` bytes will be read into `buffer`, otherwise up to `buffer.length`. If `end` == `start`, no bytes are read. Returns the number of bytes read.

## Implementation

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