Reads one or several fields. The fields are identified by index
Procedure:
H5TB_READ_FIELDS_INDEX ( loc_id, table_name, nfields, field_index, start, nrecords, type_size, field_offset, dst_sizes, data )
Signature:
herr_t H5TBread_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 *dst_sizes, void *data)
subroutine h5tbread_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 h5tbread_field_index_f
Parameters:
hid_t loc_id | IN: Identifier of the file or group to read the table within |
const char *table_name | IN: The name of the dataset to read |
int nfields | IN: The number of fields to read (This parameter is also the size of the field_index array.) |
const int * field_index | IN: The indexes of the fields to read |
hsize_t start | IN: The start record to read from |
hsize_t nrecords | IN: The number of records to read |
hsize_t type_size | IN: The size in bytes of the structure associated with the table. (This value is obtained with sizeof.) |
const size_t *field_offset | IN: An array containing the offsets of the fields |
const size_t *dst_sizes | IN: An array containing the size in bytes of the fields |
void *data | OUT: Buffer with data |
Description:
H5TB_READ_FIELDS_INDEX reads the fields identified by 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.
