Syntax
#include <eim.h>
int eimListRegistries(EimHandle * eim,
char * registryName,
char * registryType,

Threadsafe: Yes
The eimListRegistries() function lists the user registries participating in the EIM domain. The following parameters can be used to filter the results returned: registryType, registryName and registryKind.
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.
- registryName (Input)
- The name of the EIM registry to list. The name may contain the wild card
char (*). This is used as a filter to determine which registries to return.
This parameter may be NULL in which case no filtering would be done by
name.
- registryType (Input)
- A string form of an OID that represents the registry type and a user name
normalization method. The normalization method is necessary because some
registries are case-independent and others are case-dependent. EIM uses this
information to make sure the appropriate search occurs. See eim.h for a list of
defined types. This parameter may be NULL in which case no filtering would be
done by type.
- registryKind (Input)
- The kind of registry to list. This parameter is passed by value.
Valid values are:
EIM_ALL_REGISTRIES (0) System, application, and group registries will be returned. EIM_SYSTEM_REGISTRY (1) Return system registries. EIM_APPLICATION_REGISTRY (2) Return application registries. EIM_GROUP_REGISTRY (3) Return group registries.
- lengthOfListData (Input)
- The number of bytes provided by the caller for the listData
parameter. The minimum size required is 20 bytes. This parameter is passed
by value.
- listData (Output)
- A pointer to the data to be returned.
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 EimRegistry structures. firstEntry is used to get to the first EimRegistry 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;EimRegistry structure:
typedef struct EimRegistry { unsigned int nextEntry; /* Displacement to next entry. This byte offset is relative to the start of this structure */ enum EimRegistryKind kind; /* Kind of registry */ EimListData name; /* Registry name */ EimListData type; /* Registry type */ EimListData description; /* Description */ EimListData entryUUID; /* Entry UUID */ EimListData URI; /* URI */ EimListData systemRegistryName; /* System registry name */ EimSubList registryAlias; /* EimRegistryAlias sublist */ enum EimStatus mappingLookup; /* Mapping lookup attribute */ enum EimStatus policyAssociations; /* Policy associations attribute */EimSubList registryMembers; /* EimRegistryName sublist */ EimSubList registryGroups; /* EimRegistryName sublist */} EimRegistry;
Registries may have a number of aliases defined. In the EimRegistry structure, the registryAlias EimSubList gives addressability to the first EimRegistryAlias structure.
EimRegistryAlias structure:
typedef struct EimRegistryAlias { unsigned int nextEntry; /* Displacement to next entry. This byte offset is relative to the start of this structure */ EimListData type; /* Alias type */ EimListData value; /* Alias value */ } EimRegistryAlias;Group registries may have a number of members defined. In the EimRegistry structure, the registryMembers EimSubList gives addressability to the first EimRegistryName structure. Registry members will only exist for registries that have a type of group registry.
Registries may have a number of group registries of which they are a member. In the EimRegistry structure, the registryGroups EimSubList gives addressability to the first EimRegistryName structure. Registry groups will only exist for registries that are not group registries.
EimRegistryName structure:
typedef struct EimRegistryName { unsigned int nextEntry; /* Displacement to next entry. This byte offset is relative to the start of this structure */ EimListData name; /* Name. */ } EimRegistryName;EimSubList structure:
typedef struct EimSubList { unsigned int listNum; /* Number of entries in the list */ unsigned int disp; /* Displacement to sublist. This byte offset is relative to the start of the parent structure; that is, the structure containing this structure. */ } EimSubList;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.

- Access denied. Not enough permissions to access data.
EIMERR_ACCESS (1) Insufficient access to EIM data.
- EBADDATA
- eimrc is not valid.
- EBUSY
- Unable to allocate internal system object.
EIMERR_NOLOCK (26) Unable to allocate internal system object.

- Data conversion error.
EIMERR_DATA_CONVERSION (13) Error occurred when converting data between code pages.
- EINVAL
- Input parameter was 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_PARM_REQ (34) Missing required parameter. Please check API documentation. EIMERR_PTR_INVAL (35) Pointer parameter is not valid. EIMERR_REGKIND_INVAL (38) Requested registry kind 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

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_UNKNOWN (44) Unknown error or unknown system state.
