Re^5: Stumped with select->can_read (buffered)

[zentara]

Would it be horrible (performance wise) to read one byte at a time until I reach a newline character, thus forming a real $line?

It's been done before. :-) It certainly is inefficient. What I would do, is sysread as big of chunks as you can, then concat everything into a temp buffer, then split the buffer on newlines into an @array. If the scalar @array is greater than 1, then you have a line. Return the last @array element to your $temp_buffer, and process the rest of the @array elements as lines. It's called a sliding buffer, and you can google for "perl sliding buffer" for examples.

sysread can read onto the end of the buffer, avoiding the need to copy the data again:

    sysread( $fh, $buf, 16*1024, length($buf) );
