Function Documentation

LBMPDMExpDLL int lbmpdm_cache_init ( uint32_t cache_size )

initialize the cache for a given number of buckets. If 0 is given the the cache will default. The default can be altered via a PDM attribute.

Parameters

cache_size – how many buckets should this hash contain? If set to zero this will default.

LBMPDMExpDLL int lbmpdm_cache_struct_add ( lbmpdm_defn_t * defn )

add a definition structure to the cache. It is assumed that the structure has a unique id, if the id is set to zero the structure will not be inserted into the map.

Parameters

defn	– the new definition structure being added.

LBMPDMExpDLL int lbmpdm_cache_struct_find	(	lbmpdm_defn_t **	defn,
		int32_t	id
	)

find a given definition structure by id and return the structure for it. Returns PDM_FAILURE for nothing found, and PDM_SUCCESS for something found. Note, since a structure with the id of 0 won't exist in the cache you will never find one being returned from this find with an id of 0.

Parameters

defn	– pointer to the structure to return. This field is not altered if nothing is found for a given id.
id	– id to search for in the hash.

LBMPDMExpDLL int lbmpdm_cache_struct_find_by_version	(	lbmpdm_defn_t **	defn,
		int32_t	id,
		uint8_t	vers_major,
		uint8_t	vers_minor
	)

find a given definition structure by id, major version, and minor version and return the structure for it. Returns PDM_FAILURE for nothing found, and PDM_SUCCESS for something found. Note, since a structure with the id of 0 won't exist in the cache you will never find one being returned from this find with an id of 0.

Parameters

defn	– pointer to the structure to return. This field is not altered if nothing is found for a given id.

LBMPDMExpDLL lbmpdm_field_handle_t lbmpdm_defn_add_field_info_by_int_name	(	lbmpdm_defn_t *	defn,
		int32_t	int_name,
		int16_t	type,
		lbmpdm_field_info_attr_t *	info_attr
	)

adds field info to the definition by integer name

Parameters

defn	– A pointer to a PDM defn object.
int_name	– the integer name
type	– the PDM field type
info_attr	– the field information attributes

Returns: PDM_SUCCESS or PDM_FAILURE

LBMPDMExpDLL lbmpdm_field_handle_t lbmpdm_defn_add_field_info_by_str_name	(	lbmpdm_defn_t *	defn,
		const char *	str_name,
		int16_t	type,
		lbmpdm_field_info_attr_t *	info_attr
	)

adds field info to the definition by string name

Parameters

defn	– A pointer to a PDM defn object.
str_name	– the string name
type	– the PDM field type
info_attr	– the field information attributes

Returns: PDM_SUCCESS or PDM_FAILURE

LBMPDMExpDLL int lbmpdm_defn_create	(	lbmpdm_defn_t **	defn,
		int32_t	num_fields,
		int32_t	id,
		int8_t	vrs_mjr,
		int8_t	vrs_mnr,
		uint8_t	field_names_type
	)

Create a definition, with the passed number of fields. The num_fields is required to be at least 1. The number of fields can grow beyond this value, it is used initially to size the internal field info array.

Parameters

defn	– pointer to newly created definition.
num_fields	– how many fields to initially assume we will have, this is for optimization, not a limit to how many fields.
id	– This is the id for the definition. It is assumed that this is a unique id.
vrs_mjr	– A version major number to be assigned to the newly created definition. When deserializing a message, PDM will attempt to use the existing set definition if the ids match. If the message flag is set to use the included message definition or try to load the definition from the cache, then an attempt will be made to replace the set definition with the new one by its version numbers. Please note: when versioning message definitions, adding optional fields only is the safest way to unsure interoperability with older versions. Adding new required fields or modifying the types of existing required fields may lead to messages that are not deserializable by receivers with older definition versions.
vrs_mnr	– A version minor number
field_names_type	– A type that indicates whether the field names will be strings or ints. Use either PDM_DEFN_STR_FIELD_NAMES or PDM_DEFN_INT_FIELD_NAMES for the value.

Returns: PDM_SUCCESS or PDM_FAILURE.

LBMPDMExpDLL int lbmpdm_defn_delete ( lbmpdm_defn_t * defn )

delete a given definition.

Parameters

defn	– definition to be deleted.

Returns: PDM_SUCCESS or PDM_FAILURE.

LBMPDMExpDLL int lbmpdm_defn_deserialize	(	lbmpdm_defn_t *	defn,
		const char *	bufptr,
		uint32_t	buflen,
		uint8_t	swap_bytes
	)

Deserialize the associated buffer into a newly created defn.

This will take the passed buffer and deserialize the contents into a newly created defn. When finished with the defn, the caller must call lbmpdm_defn_delete() to properly dispose of the defn. This is done automatically by a message when the defn is included. The message normally indicates to the definition whether or not swap bytes need to be set to PDM_TRUE so to use this method directly, this knowledge must be determined outside PDM.

See also: lbmpdm_msg_delete()

Parameters

defn	A pointer to a previously created PDM defn object

buflen	The length of the buffer.
swap_bytes	Whether or not bytes should be swapped to deal with endianness.

Returns: PDM_SUCCESS if successful or PDM_FAILURE otherwise.
