h5part_int64_t H5PartCloseFile

(

H5PartFile *

f

)

Closes an open file.

Returns:

H5PART_SUCCESS or error code

Parameters:

[in]

f

filehandle of the file to close

H5PartFile* H5PartOpenFile	(	const char *	filename,
		const char	flags
	)

Opens file with specified filename.

Flags are bit values that can be combined with the bit operator | and include:

• H5PART_WRITE - truncate file and open for writing
• H5PART_APPEND - open file for writing without truncating
• H5PART_READ - open file read-only

The typical file extension is .h5.

H5PartFile should be treated as an essentially opaque datastructure. It acts as the file handle, but internally it maintains several key state variables associated with the file.

Returns:

File handle or NULL

Parameters:

[in]	filename	The name of the data file to open.
[in]	flags	The access mode for the file.

H5PartFile* H5PartOpenFileAlign	(	const char *	filename,
		const char	flags,
		h5part_int64_t	align
	)

Opens file with specified filename, and also specifices an alignment value used for HDF5 tuning parameters.

Flags are bit values that can be combined with the bit operator | and include:

• H5PART_WRITE - truncate file and open for writing
• H5PART_APPEND - open file for writing without truncating
• H5PART_READ - open file read-only

The typical file extension is .h5.

H5PartFile should be treated as an essentially opaque datastructure. It acts as the file handle, but internally it maintains several key state variables associated with the file.

Returns:

File handle or NULL

Parameters:

[in]	filename	The name of the data file to open.
[in]	flags	The access mode for the file.
[in]	align	Alignment size in bytes.

H5PartFile* H5PartOpenFileParallel	(	const char *	filename,
		const char	flags,
		MPI_Comm	comm
	)

Opens file with specified filename.

Flags are bit values that can be combined with the bit operator | and include:

• H5PART_WRITE - truncate file and open for writing
• H5PART_APPEND - open file for writing without truncating
• H5PART_READ - open file read-only
• H5PART_FS_LUSTRE - enable optimizations for the Lustre file system
• H5PART_VFD_MPIPOSIX - use the HDF5 MPI-POSIX virtual file driver
• H5PART_VFD_MPIO_IND - use MPI-IO in indepedent mode

The typical file extension is .h5.

H5PartFile should be treated as an essentially opaque datastructure. It acts as the file handle, but internally it maintains several key state variables associated with the file.

Returns:

File handle or NULL

Parameters:

[in]	filename	The name of the data file to open.
[in]	flags	The access mode for the file.
[in]	comm	MPI communicator

H5PartFile* H5PartOpenFileParallelAlign	(	const char *	filename,
		const char	flags,
		MPI_Comm	comm,
		h5part_int64_t	align
	)

Opens file with specified filename, and also specifices an alignment value used for HDF5 tuning parameters.

Flags are bit values that can be combined with the bit operator | and include:

• H5PART_WRITE - truncate file and open for writing
• H5PART_APPEND - open file for writing without truncating
• H5PART_READ - open file read-only
• H5PART_FS_LUSTRE - enable optimizations for the Lustre file system

[in]	flags	The access mode for the file.
[in]	comm	MPI communicator
[in]	align	Alignment size in bytes.

h5part_int64_t H5PartSetVerbosityLevel

(

h5part_int64_t
