What about the case where read() returns 0, e.g., when reading from a socket,
but subsequent reads return positive values?
// read to EOF which may read more or less than buffer size
while ((n = read(buf, nread, buf.length - nread)) > 0) {
nread += n;
}
Then it does not look as if buffer is full or am I mistaken?
Thanks,
