/// # Brief I/O
///
/// ```text
/// VARIABLE I/O DESCRIPTION
/// -------- --- --------------------------------------------------
/// HANDLE I Handle of the SPK file to be closed.
/// ```
///
/// # Detailed Input
///
/// ```text
/// HANDLE is the handle of the SPK file that is to be closed.
/// ```
///
/// # Exceptions
///
/// ```text
/// 1) If there are no segments in the file, the error
/// SPICE(NOSEGMENTSFOUND) is signaled.
/// ```
///
/// # Files
///
/// ```text
/// See argument HANDLE.
/// ```
///
/// # Particulars
///
/// ```text
/// Close the SPK file attached to HANDLE. The close operation tests
/// the file to ensure the presence of data segments.
///
/// A SPKCLS call should balance each call to SPKOPN.
/// ```
///
/// # Examples
///
/// ```text
/// The numerical results shown for this example may differ across
/// platforms. The results depend on the SPICE kernels used as
/// input, the compiler and supporting libraries, and the machine
