/// EK, update d.p. column entry

/// * [EK](crate::required_reading::ek)
///
/// # Brief I/O
///
/// ```text
///  VARIABLE  I/O  DESCRIPTION
///  --------  ---  --------------------------------------------------
///  HANDLE     I   Handle attached to EK file.
///  SEGNO      I   Index of segment containing record.
///  RECNO      I   Record in which entry is to be updated.
///  COLUMN     I   Column name.
///  NVALS      I   Number of values in new column entry.
///  DVALS      I   Double precision values to add to column.
///  ISNULL     I   Flag indicating whether column entry is null.
/// ```
///
/// # Detailed Input
///
/// ```text
///  HANDLE   is a file handle attached to an EK open for
///           write access.
///
///  SEGNO    is the index of the segment containing the column
///           entry to be updated.
///
///  RECNO    is the index of the record containing the column
///           entry to be updated. This record number is
///           relative to the start of the segment indicated by
///           SEGNO; the first record in the segment has index 1.
///
///  COLUMN   is the name of the column containing the entry to
///           be updated.
///
///  NVALS,
///  DVALS    are, respectively, the number of values to add to
///           the specified column and the set of values
///           themselves. The data values are written in to the
///           specified column and record.
///
///           If the  column has fixed-size entries, then NVALS
///           must equal the entry size for the specified column.
///
///           For columns with variable-sized entries, the size
///           of the new entry need not match the size of the
///           entry it replaces. In particular, the new entry
///           may be larger.
///
///  ISNULL   is a logical flag indicating whether the entry is
///           null. If ISNULL is .FALSE., the column entry
///           defined by NVALS and DVALS is added to the
///           specified kernel file.
///
///           If ISNULL is .TRUE., NVALS and DVALS are ignored.
///           The contents of the column entry are undefined.
///           If the column has fixed-length, variable-size
///           entries, the number of entries is considered to
///           be 1.
///
///           The new entry may be null even though it replaces
///           a non-null value, and vice versa.
/// ```
///
/// # Detailed Output
///
/// ```text
///  None. See $Particulars for a description of the effect of this
///  routine.
/// ```
///
/// # Exceptions
///
/// ```text
///  1)  If HANDLE is invalid, an error is signaled by a routine in the
///      call tree of this routine.
///
///  2)  If SEGNO is out of range, an error is signaled by a routine in
///      the call tree of this routine.
///
///  3)  If COLUMN is not the name of a declared column, an error
///      is signaled by a routine in the call tree of this routine.
///
///  4)  If COLUMN specifies a column of whose data type is not DOUBLE
///      PRECISION or TIME, the error SPICE(WRONGDATATYPE) is signaled.
///
///  5)  If RECNO is out of range, an error is signaled by a routine in
///      the call tree of this routine.
///
///  6)  If the specified column has fixed-size entries and NVALS does
///      not match this size, an error is signaled by a routine in the
///      call tree of this routine.
///
///  7)  If the specified column has variable-size entries and NVALS is
///      non-positive, an error is signaled by a routine in the call
///      tree of this routine.
///
///  8)  If an attempt is made to add a null value to a column that
///      doesn't take null values, an error is signaled by a routine in
///      the call tree of this routine.
///
///  9)  If COLUMN specifies a column of whose class is not
///      a double precision class known to this routine, the error
///      SPICE(NOCLASS) is signaled.
///
///  10) If an I/O error occurs while reading or writing the indicated
///      file, the error is signaled by a routine in the call tree of
///      this routine.
/// ```

/// # Files
///
/// ```text
///  See the EK Required Reading ek.req for a discussion of the EK file
///  format.
/// ```
///
/// # Particulars
///
/// ```text
///  This routine operates by side effects: it modifies the named
///  EK file by adding data to the specified record in the specified
///  column. Data may be added to a segment in random order; it is not
///  necessary to fill in columns or rows sequentially. Data may only
///  be added one logical element at a time. Partial assignments of
///  logical elements are not supported.
///
///  Since columns of data type TIME are implemented using double
///  precision column classes, this routine may be used to update
///  columns of type TIME.
/// ```
///
/// # Examples
///
/// ```text
///  1)  Replace the value in the third record of the column DCOL in
///      the fifth segment of an EK file designated by HANDLE. Set
///      the new value to 999.D0.
///
///         CALL EKUCED ( HANDLE, 5, 3, 'DCOL', 1, 999.D0, .FALSE. )
///
///
///  2)  Same as (1), but this time add a null value. The argument
///      999.D0 is ignored because the null flag is set to .TRUE.
///
///         CALL EKUCED ( HANDLE, 5, 3, 'DCOL', 1, 999.D0, .TRUE. )
///
///
///  3)  Replace the entry in the third record of the column DARRAY in
///      the fifth segment of an EK file designated by HANDLE. Set
///      the new value using an array DBUFF of 10 d.p. values.
///
///         CALL EKUCED ( HANDLE, 5, 3, 'DARRAY', 10, DBUFF, .FALSE. )
