H5TB_WRITE_FIELDS_INDEX

Overwrites fields.

Procedure:

H5TB_WRITE_FIELDS_INDEX(loc_id, table_name, nfields, field_index, start, nrecords, type_size, field_offset, field_sizes, data)

Signature:

herr_t H5TBwrite_fields_index ( 
              hid_t loc_id, 
              const char *table_name, 
              int nfields, 
              const int *field_index, 
              hsize_t start, 
              hsize_t nrecords, 
              size_t type_size,
              const size_t *field_offset,
              const size_t* field_sizes, 
              const void *data
         )

subroutine h5tbwrite_field_index_f(loc_id, dset_name, field_index, start, &
                                   nrecords, type_size, buf, errcode)
  implicit none
  integer(HID_T), intent(IN) :: loc_id           ! file or group identifier 
  character(LEN=*), intent(IN) :: dset_name      ! name of the dataset 
  integer, intent(IN) :: field_index             ! index
  integer(HSIZE_T), intent(IN) :: start          ! start record 
  integer(HSIZE_T), intent(IN) :: nrecords       ! records
  integer(SIZE_T), intent(IN) :: type_size       ! type size
  , intent(IN), dimension(*) :: buf        ! data buffer 
  integer :: errcode                             ! error code
end subroutine h5tbwrite_field_index_f

Parameters:

    hid_t loc_id

        IN: Identifier of the file or group where the table is located.

    const char *table_name

        IN: The name of the dataset to overwrite.

    int nfields

        IN: The number of fields to overwrite. This parameter is also the size of the field_index array.

    const int *field_index

        IN: The indexes of the fields to write.

    hsize_t start

        IN: The zero based index record to start writing.  

    hsize_t nrecords

        IN: The number of records to write.

    size_t type_size

        IN: The size of the structure type, as calculated by sizeof().

    const size_t *field_offset

        IN: An array containing the offsets of the fields. These offsets can be calculated with the HOFFSET macro.

    const size_t *field_sizes

        IN: An array containing the sizes of the fields.

    void *data

        IN: Buffer with data.

Description:

H5TBwrite_fields_index overwrites one or several fields contained in the buffer field_index from a dataset named table_name attached to the object specified by the identifier loc_id. 

Returns:

Returns a non-negative value if successful; otherwise returns a negative value.

Example:

int
main (void)
{
    hsize_t     dims[2], dimsm[2];   
    int         data[DIM0][DIM1];           /* data to write */
    int         sdata[DIM0_SUB][DIM1_SUB];  /* subset to write */
    int         rdata[DIM0][DIM1];          /* buffer for read */
 
    hid_t       file_id, dataset_id;        /* handles */
    hid_t       dataspace_id, memspace_id;
