示例1: read
import com.lody.virtual.helper.utils.ArrayUtils; //導入方法依賴的package包/類
/**
* java.io thinks that a read at EOF is an error and should return -1, contrary to traditional
* Unix practice where you'd read until you got 0 bytes (and any future read would return -1).
*/
public static int read(FileDescriptor fd, byte[] bytes, int byteOffset, int byteCount) throws IOException {
ArrayUtils.checkOffsetAndCount(bytes.length, byteOffset, byteCount);
if (byteCount == 0) {
return 0;
}
try {
int readCount = Os.read(fd, bytes, byteOffset, byteCount);
if (readCount == 0) {
return -1;
}
return readCount;
} catch (ErrnoException errnoException) {
if (errnoException.errno == OsConstants.EAGAIN) {
// We return 0 rather than throw if we try to read from an empty non-blocking pipe.
return 0;
}
throw new IOException(errnoException);
}
}
示例2: write
import com.lody.virtual.helper.utils.ArrayUtils; //導入方法依賴的package包/類
/**
* java.io always writes every byte it's asked to, or fails with an error. (That is, unlike
* Unix it never just writes as many bytes as happens to be convenient.)
*/
public static void write(FileDescriptor fd, byte[] bytes, int byteOffset, int byteCount) throws IOException {
ArrayUtils.checkOffsetAndCount(bytes.length, byteOffset, byteCount);
if (byteCount == 0) {
return;
}

while (byteCount > 0) {
int bytesWritten = Os.write(fd, bytes, byteOffset, byteCount);
byteCount -= bytesWritten;
byteOffset += bytesWritten;
}
} catch (ErrnoException errnoException) {
