示例1: readLine
LineReader::State LineReader::readLine(StringPiece& line) {
bol_ = eol_; // Start past what we already returned
for (;;) {
// Search for newline
char* newline = static_cast<char*>(memchr(eol_, '\n', end_ - eol_));
if (newline) {
eol_ = newline + 1;
break;
} else if (state_ != kReading || (bol_ == buf_ && end_ == bufEnd_)) {
// If the buffer is full with one line (line too long), or we're
// at the end of the file, return what we have.
eol_ = end_;
break;
}
// We don't have a full line in the buffer, but we have room to read.
// Move to the beginning of the buffer.
memmove(buf_, eol_, end_ - eol_);
end_ -= (eol_ - buf_);
bol_ = buf_;
eol_ = end_;
// Refill
ssize_t available = bufEnd_ - end_;
