Function Documentation

pressio_io_data_path_h5read()

struct pressio_data * pressio_io_data_path_h5read	(	const char *	file_name,
		const char *	dataset_name
	)

reads files that use simple datatypes and dataspaces into a pressio_data

The following are not supported:

• complex datatypes or dataspaces
• unlimited dimension datasets.

Parameters

[in]	file_name	name of the file to read
[in]	dataset_name	name of the dataset to read from the file

Returns

a pressio_data structure or nullptr if there was an error

pressio_io_data_path_h5write()

int pressio_io_data_path_h5write	(	struct pressio_data const *	data,
		const char *	file_name,
		const char *	dataset_name
	)

writes files that use simple datatypes and dataspaces from a pressio_data

if the file already exists, it will be opened. if the file does not exist, it will be created. if the dataset already exists, it will be overwritten. if the dataset does not exist, it will be created.

Parameters

[in]	data	the data to be written
[in]	file_name	name of the file to written
[in]	dataset_name	name of the dataset to written to the file

Returns

a 0 if successful, nonzero on error
