Closing a C++ FILE pointer which uses a file descriptor from Java

Question

When using a file descriptor in native code, which has been obtained from a ParcelFileDescriptor, should the native side use fclose after an fdopen?

The documentation states that the ParcelaleFileDescriptor instance owns the file descriptor, and it should be closed through it. I don't know the impact of closing the native FILE pointer before closing the file descriptor.

Pseudocode:

1) JAVA:
    // Obtain the file descriptor and pass it to the native method
    ParcelFileDescriptor descriptor  = contentResolver.openFileDescriptor(uri, "w");
    nativeMethod(descriptor.getFD());

2) C++:
    void nativeMethod(const int fd)
    {
        FILE* fp = fdopen(fd, "wb");    

        ..... // do something

        fclose(fp); // Close the file pointer <-- Is this valid?
    }

3) JAVA:
    // Back from the native method, close the file descriptor
    descriptor.close();
