Detailed Description

Use file creation properties to control aspects of file creation such as setting a file space management strategy or creating a user block. Unlike file access properties, creation properties are stored with the file, and cannot be changed once a file has been created.

Retrieves shared object header message phase change information.

Parameters

[in]	plist_id	File creation property list identifier
[out]	max_list	Threshold above which storage of a shared object header message index shifts from list to B-tree
[out]	min_btree	Threshold below which storage of a shared object header message index reverts to list format

Returns: Returns a non-negative value if successful; otherwise, returns a negative value.

H5Pget_shared_mesg_phase_change() retrieves the threshold values for storage of shared object header message indexes in a file. These phase change thresholds determine the point at which the index storage mechanism changes from a more compact list format to a more performance-oriented B-tree format, and vice-versa.

By default, a shared object header message index is initially stored as a compact list. When the number of messages in an index exceeds the specified max_list threshold, storage switches to a B-tree format for improved performance. If the number of messages subsequently falls below the min_btree threshold, the index will revert to the list format.

If max_list is set to 0 (zero), shared object header message indexes in the file will always be stored as B-trees.

plist_id specifies the file creation property list.

Since: 1.8.0

    H5F_FSPACE_STRATEGY_NTYPES    
} H5F_fspace_strategy_t;

This setting cannot be changed for the life of the file.

As the H5F_FSPACE_STRATEGY_AGGR and H5F_FSPACE_STRATEGY_NONE strategies do not use the free-space managers, the persist and threshold settings will be ignored for those strategies.

Since: 1.10.1

◆ H5Pset_istore_k()

herr_t H5Pset_istore_k	(	hid_t	plist_id,
		unsigned	ik )

Sets the size of the parameter used to control the B-trees for indexing chunked datasets.

Parameters

[in]	plist_id	File creation property list identifier
[in]	ik	1/2 rank of chunked storage B-tree

Returns: Returns a non-negative value if successful; otherwise, returns a negative value.

H5Pset_istore_k() sets the size of the parameter used to control the B-trees for indexing chunked datasets. This function is valid only for file creation property lists.

ik is one half the rank of a tree that stores chunked raw data. On average, such a tree will be 75% full, or have an average rank of 1.5 times the value of ik.

The HDF5 library uses (ik*2) as the maximum # of entries before splitting a B-tree node. Since only 2 bytes are used in storing # of entries for a B-tree node in an HDF5 file, (ik*2) cannot exceed 65536. The default value for ik is 32.

Version: 1.6.4 ik parameter type changed to unsigned.

Since: 1.0.0

◆ H5Pset_shared_mesg_index()

herr_t H5Pset_shared_mesg_index	(	hid_t	plist_id,
		unsigned	index_num,
		unsigned	mesg_type_flags,
		unsigned	min_mesg_size )

Configures the specified shared object header message index.

Parameters

[in]	plist_id	File creation property list identifier
[in]	index_num	Index being configured
[in]	mesg_type_flags	Types of messages that should be stored in this index
[in]	min_mesg_size	Minimum message size

Returns: Returns a non-negative value if successful; otherwise, returns a negative value.

H5Pset_shared_mesg_index() is used to configure the specified shared object header message index, setting the types of messages that may be stored in the index and the minimum size of each message.

plist_id specifies the file creation property list.

index_num specifies the index to be configured. index_num is zero-indexed, so in a file with three indexes, they will be numbered 0, 1, and 2.

mesg_type_flags and min_mesg_size specify, respectively, the types and minimum size of messages that can be stored in this index.

Valid message types are as follows:

H5O_SHMESG_NONE_FLAG	No shared messages
H5O_SHMESG_SDSPACE_FLAG	Simple dataspace message
H5O_SHMESG_DTYPE_FLAG	Datatype message
H5O_SHMESG_FILL_FLAG	Fill value message

H5O_SHMESG_ATTR_FLAG	Attribute message
H5O_SHMESG_ALL_FLAG	All message types; i.e., equivalent to the following: (H5O_SHMESG_SDSPACE_FLAG \| H5O_SHMESG_DTYPE_FLAG \| H5O_SHMESG_FILL_FLAG \| H5O_SHMESG_PLINE_FLAG \| H5O_SHMESG_ATTR_FLAG)

Since: 1.8.0

◆ H5Pset_shared_mesg_nindexes()

herr_t H5Pset_shared_mesg_nindexes	(	hid_t	plist_id,
		unsigned	nindexes )

Sets number of shared object header message indexes.

Parameters

[in]	plist_id	File creation property list identifier
[in]	nindexes	Number of shared object header message indexes to be available in files created with this property list (`nindexes` must be <= H5O_SHMESG_MAX_NINDEXES (8))

Returns: Returns a non-negative value if successful; otherwise, returns a negative value.

H5Pset_shared_mesg_nindexes() sets the number of shared object header message indexes in the specified file creation property list.

This setting determines the number of shared object header message indexes, nindexes, that will be available in files created with this property list. These indexes can then be configured with H5Pset_shared_mesg_index().

If nindexes is set to 0 (zero), shared object header messages are disabled in files created with this property list.

There is a limit of H5O_SHMESG_MAX_NINDEXES (8) that can be set with H5Pset_shared_mesg_nindexes(). An error will occur if specifying a value of nindexes that is greater than this value.

Since: 1.8.0

◆ H5Pset_shared_mesg_phase_change()

herr_t H5Pset_shared_mesg_phase_change	(	hid_t	plist_id,
		unsigned	max_list,
		unsigned	min_btree )

Sets shared object header message storage phase change thresholds.

Parameters

[in]	plist_id	File creation property list identifier
[in]	max_list	Threshold above which storage of a shared object header message index shifts from list to B-tree
[in]	min_btree	Threshold below which storage of a shared object header message index reverts to list format

Returns: Returns a non-negative value if successful; otherwise, returns a negative value.

H5Pset_shared_mesg_phase_change() sets threshold values for storage of shared object header message indexes in a file. These phase change thresholds determine the point at which the index storage mechanism changes from a more compact list format to a more performance-oriented B-tree format, and vice-versa.

By default, a shared object header message index is initially stored as a compact list. When the number of messages in an index exceeds the threshold value of max_list, storage switches to a B-tree for improved performance. If the number of messages subsequently falls below the min_btree threshold, the index will revert to the list format.

If max_list is set to 0 (zero), shared object header message indexes in the file will be created as B-trees and will never revert to lists.

plist_id specifies the file creation property list.

Since: 1.8.0

◆ H5Pset_sizes()

herr_t H5Pset_sizes	(	hid_t	plist_id,
		size_t	sizeof_addr,
		size_t	sizeof_size )

Sets the byte size of the offsets and lengths used to address objects in an HDF5 file.

Parameters

[in]	plist_id	File creation property list identifier
[in]	sizeof_addr	Size of an object offset in bytes
[in]	sizeof_size	Size of an object length in bytes

Returns: Returns a non-negative value if successful; otherwise, returns a negative value.

H5Pset_sizes() sets the byte size of the offsets and lengths used to address objects in an HDF5 file. This function is only valid for file creation property lists. Passing in a value of 0 for one of the parameters retains the current value. The default value for both values is the same as sizeof(hsize_t) in the library (normally 8 bytes). Valid values currently are 2, 4, 8 and 16.

Since: 1.0.0

◆ H5Pset_sym_k()

herr_t H5Pset_sym_k	(	hid_t	plist_id,
		unsigned	ik,
		unsigned	lk )

Parameters

[in]	plist_id	File creation property list identifier
[in]	ik	Symbol table tree rank
[in]	lk	Symbol table node size

Returns: Returns a non-negative value if successful; otherwise, returns a negative value.

H5Pset_sym_k() sets the size of parameters used to control the symbol table nodes.

This function is valid only for file creation property lists. Passing in a value of zero (0) for one of the parameters retains the current value.

ik is one half the rank of a B-tree that stores a symbol table for a group. Internal nodes of the symbol table are on average 75% full. That is, the average rank of the tree is 1.5 times the value of ik. The HDF5 library uses (ik*2) as the maximum # of entries before splitting a B-tree node. Since only 2 bytes are used in storing # of entries for a B-tree node in an HDF5 file, (ik*2) cannot exceed 65536. The default value for ik is 16.

lk is one half of the number of symbols that can be stored in a symbol table node. A symbol table node is the leaf of a symbol table tree which is used to store a group. When symbols are inserted randomly into a group, the group's symbol table nodes are 75% full on average. That is, they contain 1.5 times the number of symbols specified by lk. The default value for lk is 4.

Version: 1.6.4 ik parameter type changed to unsigned.; 1.6.0 The ik parameter has changed from type int to unsigned.

Since: 1.0.0

◆ H5Pset_userblock()

herr_t H5Pset_userblock	(	hid_t	plist_id,
		hsize_t	size )

Sets user block size.

Parameters

[in]	plist_id	File creation property list identifier
[in]	size	Size of the user-block in bytes

Returns: Returns a non-negative value if successful; otherwise, returns a negative value.

H5Pset_userblock() sets the user block size of a file creation property list. The default user block size is 0; it may be set to any power of 2 equal to 512 or greater (512, 1024, 2048, etc.).

Since: 1.0.0
