The size of the lock range
Returns the position within the file of the first byte of the locked region.
Returns the position within the file of the first byte of the locked region. A locked region need not be contained within, or even overlap, the actual underlying file, so the value returned by this method may exceed the file's current size.
Returns the size of the locked region in bytes.
Returns the size of the locked region in bytes. A locked region need not be contained within, or even overlap, the actual underlying file, so the value returned by this method may exceed the file's current size.
