eimListAssociations()--List EIM Associations
Syntax
#include <eim.h> int eimListAssociations(EimHandle * eim, enum EimAssociationType associationType, EimIdentifierInfo * idName, unsigned int lengthOfListData, EimList * listData, EimRC * eimrc)Service Program Name: QSYS/QSYEIM
Default Public Authority: *USE
Threadsafe: Yes
The eimListAssociations() function returns a list of associations for a given EIM identifier. This can be used to find all of the associated identities for an individual in the enterprise.
Authorities and Locks
- EIM Data
- Access to EIM data is controlled by EIM access groups. LDAP administrators
also have access to EIM data. The access groups whose members have authority to
the EIM data for this API follow:
- EIM Administrator
- EIM Registries Administrator
- EIM Identifiers Administrator
- EIM Mapping Lookup
- EIM authority to an individual registry
The list returned contains only the information that the user has authority to access.
Parameters
- eim (Input)
- The EIM handle returned by a previous call to eimCreateHandle(). A valid
connection is required for this function.
- associationType (Input)
- The type of association to be listed. This parameter is passed by value.
Valid values are:
EIM_ALL_ASSOC (0) List all target, source, and administrative associations. EIM_TARGET (1) List target associations. EIM_SOURCE (2) List source associations. EIM_SOURCE_AND_TARGET (3) List both source and target associations. EIM_ADMIN (4) List administrative associations.
- idName (Input)
- A structure that contains the identifier name whose associations are to be
listed. The layout of the EimIdentifierInfo structure follows:
enum EimIdType { EIM_UNIQUE_NAME, EIM_ENTRY_UUID, EIM_NAME }; typedef struct EimIdentifierInfo { union { char * uniqueName; char * entryUUID; char * name; } id; enum EimIdType idtype; } EimIdentifierInfo;
idtype indicates which identifier name is provided. Use of the uniqueName provides the best performance. Specifying an idtype of EIM_NAME does not guarantee that a unique EIM identifier will be found. Therefore, use of EIM_NAME may result in an error.
- lengthOfListData (Input)
- The number of bytes provided by the caller for the listData
parameter. Minimum size required is 20 bytes. This parameter is passed by
value.
- listData (Output)
- A pointer to the EimList structure.
The EimList structure contains information about the returned data. The API will return as much data as space has been provided. The data returned is a linked list of EimAssociation structures. firstEntry is used to get to the first EimAssociation structure in the linked list.
EimList structure:
typedef struct EimList { unsigned int bytesReturned; /* Number of bytes actually returned by the API */ unsigned int bytesAvailable; /* Number of bytes of available data that could have been returned by the API */ unsigned int entriesReturned; /* Number of entries actually returned by the API */ unsigned int entriesAvailable; /* Number of entries available to be returned by the API */ unsigned int firstEntry; /* Displacement to the first linked list entry. This byte offset is relative to the start of the EimList structure. */ } EimList;
EimAssociation structure:
typedef struct EimAssociation { unsigned int nextEntry; /* Displacement to next entry. This byte offset is relative to the start of this structure */ enum EimAssociationType associationType; /* Type of association */ EimListData registryType; /* Registry type */ EimListData registryName; /* Registry name */ EimListData registryUserName; /* Registry user name */ } EimAssociation;
EimListData structure:
typedef struct EimListData { unsigned int length; /* Length of data */ unsigned int disp; /* Displacement to data. This byte offset is relative to the start of the parent structure; that is, the structure containing this structure. */ } EimListData;
- eimrc (Input/Output)
- The structure in which to return error code information. If the return
value is not 0, eimrc is set with additional information. This parameter may be
NULL. For the format of the structure, see EimRC--EIM
Return Code Parameter.
Return Value
The return value from the API. Following each return value is the list of possible values for the messageCatalogMessageID field in the eimrc parameter for that value.
- 0
- Request was successful.
- EACCES
- Access denied. Not enough permissions to access data.
EIMERR_ACCESS (1) Insufficient access to EIM data.
- EBADDATA
- eimrc is not valid.
- EBADNAME
- Identifier name is not valid or insufficient access to EIM data.
EIMERR_IDNAME_AMBIGUOUS (20) More than 1 EIM Identifier was found that matches the requested Identifier name. EIMERR_NOIDENTIFIER (25) EIM Identifier not found or insufficient access to EIM data.
- EBUSY
- Unable to allocate internal system object.
EIMERR_NOLOCK (26) Unable to allocate internal system object.
- ECONVERT
- Data conversion error.
EIMERR_DATA_CONVERSION (13) Error occurred when converting data between code pages.
- EINVAL
- Input parameter was not valid.
EIMERR_ASSOC_TYPE_INVAL (4) Association type is not valid. EIMERR_EIMLIST_SIZE (16) Length of EimList is not valid. EimList must be at least 20 bytes in length. EIMERR_HANDLE_INVAL (17) EimHandle is not valid. EIMERR_IDNAME_TYPE_INVAL (52) The EimIdType value is not valid. EIMERR_PARM_REQ (34) Missing required parameter. Please check API documentation. EIMERR_PTR_INVAL (35) Pointer parameter is not valid. EIMERR_SPACE (41) Unexpected error accessing parameter.
- ENOMEM
- Unable to allocate required space.
EIMERR_NOMEM (27) No memory available. Unable to allocate required space.
- ENOTCONN
- LDAP connection has not been made.
EIMERR_NOT_CONN (31) Not connected to LDAP. Use eimConnect() API and try the request again.
- EUNKNOWN
- Unexpected exception.
EIMERR_LDAP_ERR (23) Unexpected LDAP error. %s EIMERR_UNEXP_OBJ_ VIOLATION (56) Unexpected object violation. EIMERR_UNKNOWN (44) Unknown error or unknown system state.
