◆ DS_Entry_GetNamedAttr()

DS_Status DS_Entry_GetNamedAttr	(	const DS_Entry *	entry,
		const char *	type,
		const DS_Attr **	attr_p
	)

Get the named attribute from an attribute list.

This works only with normal entries (not change-entries). For known attribute-types, this matches correctly by alias or normal name. For unknown attribute-types it matches only by the name provided.

Parameters

[in]	entry	Source directory entry (a normal entry).
[in]	type	Attribute type name.
[out]	attr_p	Return DS_Attr pointer.

Return values

DS_E_BADPARAM	Either entry or type or attr_p was NULL, or type was "", or entry is a change-entry.
DS_E_BADATTRTYPE	The type is unknown to the schema, and was not found in the entry.
DS_E_NOTFOUND	The type is known to the schema, but was not found in the entry.

◆ DS_Entry_GetAttrList()

DS_Status DS_Entry_GetAttrList	(	const DS_Entry *	entry,
		const DS_AttrList **	attr_list_p
	)

Get the entry attribute list.

This works only with normal entries (not change-entries).

Parameters

[in]	entry	Source directory entry (a normal entry, usually).
[out]	attr_list_p	Return attribute list (NULL if this is a change-entry)

Return values

DS_E_BADPARAM	If entry was NULL
DS_E_NOERROR	The DS_AttrList was returned

Examples: async.c, and read.c.

◆ DS_Entry_GetModList()

DS_Status DS_Entry_GetModList	(	const DS_Entry *	entry,
		const DS_AttrList **	mod_list_p
	)

Get the change-entry's modification list.

This can be used to get the modification list of Modify and Add change-entries.

Parameters

[in]	entry	Source change-entry.
[out]	mod_list_p	Return attribute modification list.

Return values

DS_E_BADPARAM	If entry was NULL or entry isn't a change-entry
DS_E_NOERROR	The DS_AttrList was returned

Since: DSAPI_VERSION 2007

◆ DS_AttrList_New()

DS_Status DS_AttrList_New	(	DS_AttrList **	attrlist_p,
		const DS_Attr *	attr
	)

Create a new Attribute list. Initially the list contains a single Attribute.

Parameters

[out]	attrlist_p	Return DS_AttrList pointer.
[in]	attr	an Attribute of which a copy will be made and used as the first element in the list.

Return values

DS_E_NOERROR	a new DS_AttrList was created and returned
DS_E_BADPARAM	if attr was NULL
DS_E_NOMEMORY	an internal memory allocation failed

Since: DSAPI_VERSION 2003

◆ DS_AttrList_Append()

DS_Status DS_AttrList_Append	(	DS_AttrList *	attrlist,
		const DS_Attr *	attr
	)

Append an attribute to an Attribute list.

Parameters

[in,out]	attrlist	the Attribute list
[in]	attr	an Attribute to be appended to the list. A copy of the attribute will be made and appended to the list.

Since: DSAPI_VERSION 2003

◆ DS_AttrList_GetFirst()

const DS_Attr* DS_AttrList_GetFirst ( const DS_AttrList * attr_list )

Get the first attribute in an attribute list.

Parameters

[in] attr_list Attribute list.

Return values

NULL	If there are no attributes in the list
non-NULL	Pointer to the first attribute in the list

Examples: async.c, and read.c.

◆ DS_AttrList_GetNext()

const DS_Attr* DS_AttrList_GetNext ( const DS_Attr * attr )

Get the next attribute in a list.

Parameters

[in] attr Current attribute in list.

Return values

NULL	If there are no more attributes in the list
non-NULL	Pointer to the next attribute in the list

Examples: async.c, and read.c.

◆ DS_Attr_GetTypeName()

DS_Status DS_Attr_GetTypeName	(	const DS_Attr *	attr,
		const char **	str_p
	)

Return the type name of a given attribute.

The string returned by this function should not be freed as it points to memory fixed and resident within the API layer.

Parameters

[in]	attr	Attribute pointer
[out]	str_p	Returned string pointer.

Return values

DS_E_BADPARAM	Either attr or str_p was NULL
DS_E_NOERROR	A string was returned

		DSModType *	type_p
	)

Return the modification type of a given attribute.

If the attribute is a part of a change-entry, then this function returns the modification type: DSModAdd, DSModDelete or DSModReplace.

Parameters

[in]	attr	Attribute pointer
[out]	type_p	Returned DSModType.

Return values

	)

Get an attribute's value list.

Parameters

[in]	attr	Source attribute.
[out]	val_list_p	Returned list of values. In the case that this is the result of a read or search operation using DS_SVC_OPT_ATTRSONLY, this pointer will be set to NULL, to indicate that no attribute values are present.

Return values
