H5S_GET_SIMPLE_EXTENT_NPOINTS
Determines the number of elements in a dataspace
Procedure:
H5S_GET_SIMPLE_EXTENT_NPOINTS ( space_id )
Signature:
hssize_t H5Sget_simple_extent_npoints(
hid_t space_id
)
Fortran90 Interface: h5sget_simple_extent_npoints_f
SUBROUTINE h5sget_simple_extent_npoints_f(space_id, npoints, hdferr)
IMPLICIT NONE
INTEGER(HID_T), INTENT(IN) :: space_id ! Dataspace identifier
INTEGER(HSIZE_T), INTENT(OUT) :: npoints ! Number of elements in dataspace
INTEGER, INTENT(OUT) :: hdferr ! Error code
! 0 on success and -1 on failure
END SUBROUTINE h5sget_simple_extent_npoints_f
Parameters:
hid_t space_id IN: Identifier of the dataspace object to query
Description:
H5S_GET_SIMPLE_EXTENT_NPOINTS determines the number of elements in a dataspace space_id. For example, a simple 3-dimensional dataspace with dimensions 2, 3, and 4 would have 24 elements.
Returns:
Returns the number of elements in the dataspace if successful; otherwise returns a negative value.
Example:
if (H5T_FLOAT == H5Tget_class(atype)) {
printf("Type : FLOAT \n");
npoints = H5Sget_simple_extent_npoints(aspace);
float_array = (float *)malloc(sizeof(float)*(int)npoints);
ret = H5Aread(attr, atype, float_array);
printf("Values : ");
for( i = 0; i < (int)npoints; i++)
printf("%f ", float_array[i]);
printf("\n");
free(float_array);
}
