note mantager <p>Thanks,<br /> I was wondering if "." could change in some way the content of the two buffers. Since it's <em>string</em> concatenation operator, I was worried that some sort of "stringification" of the two buffers could change them some way (this is why I asked if there's a way to concat two <em>binary</em> buffers). I am still not sure about this. </p> <p>Regarding the size of the read data: I am actually trying to put back together some stripes from a dead raid array, so if I am not able to read exactly $bufsize bytes I'd better die away asap :) </p> <p>Thanks a lot!</p> 1003666 1003671
