Find the amount of storage allocated for a dataset — H5Dget_storage

H5Dget_storage_size returns the amount of storage, in bytes, allocated in an HDF5 file to hold a given dataset. This is the amount of space required on-disk, which not typically a good indicator of the amount of memory that will be required to read the complete dataset.

Usage

H5Dget_storage_size(h5dataset)

Arguments

h5dataset: Object of class H5IdComponent representing an open HDF5 dataset

Value

Returns an integer giving the number of bytes allocated in the file to the dataset.

Examples

f <- system.file("testfiles", "h5ex_t_array.h5", package = "rhdf5")
fid <- H5Fopen(f)
did <- H5Dopen(fid, "DS1")
H5Dget_storage_size(did)
#> [1] 480
H5Dclose(did)
H5Fclose(fid)
