H5LT_MAKE_DATASET_FLOAT
Creates and writes a dataset.
Procedure:
H5LT_MAKE_DATASET_FLOAT(loc_id, dset_name, rank, dims, buffer)
Signature:
herr_t H5LTmake_dataset_float ( hid_t loc_id, const char *dset_name, int rank, const hsize_t *dims, const float *buffer )
subroutine h5ltmake_dataset_float_f(loc_id, dset_name, rank, dims, &
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) :: rank ! rank
integer(HSIZE_T), dimension(*), intent(IN) :: dims
! size of the buffer buf
real, intent(IN), dimension(*) :: buf ! data buffer
integer :: errcode ! error code
end subroutine h5ltmake_dataset_float_f
Parameters:
hid_t loc_id | IN: Identifier of the file or group to create the dataset within. |
const char *dset_name | IN: The name of the dataset to create. |
int rank | IN: Number of dimensions of dataspace. |
const hsize_t * dims | IN: An array of the size of each dimension. |
const float * buffer | IN: Buffer with data to be written to the dataset. |
Description:
H5LTmake_dataset creates and writes a dataset named dset_name attached to the object specified by the identifier loc_id.
The dataset’s datatype will be native floating point, H5T_NATIVE_FLOAT.
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;
PROGRAM COMPOUNDEXAMPLE
USE HDF5 ! This module contains all necessary modules
IMPLICIT NONE
CHARACTER(LEN=11), PARAMETER :: filename = "compound.h5" ! File name
CHARACTER(LEN=8), PARAMETER :: dsetname = "Compound" ! Dataset name
INTEGER, PARAMETER :: dimsize = 6 ! Size of the dataset
INTEGER(HID_T) :: file_id ! File identifier
int main (void)
{

int i, j;
int data[NX][NY]; // buffer for data to write
for (j = 0; j < NX; j++)
