eimGetAttribute()--Get EIM attributes

 #include <eim.h>

 int eimGetAttribute(EimHandle          * eim,
                     enum EimHandleAttr   attrName,
                     unsigned int         lengthOfEimAttribute,
                     EimAttribute       * attribute,
         EimRC              * eimrc)

 

The eimGetAttribute() function is used to get attributes for this EIM handle.

The ldap configuration file is used to retrieve information for the master host, master port, and secure port. If the host system is not a replica then the master information retrieved is the same as the host and port defined in the handle.

Authorities and Locks

None.

Parameters

eim  (Input)

The EIM handle returned by a previous call to eimCreateHandle().

attrName  (Input)

The name of the attribute to retrieve. Following are valid values:

EIM_HANDLE_CCSID (0)	This is the CCSID of character data passed by the caller of EIM APIs with the specified EimHandle. The returned field is a 4 byte integer.
EIM_HANDLE_DOMAIN (1)	The EIM domain name.
EIM_HANDLE_HOST (2)	The host system for the EIM domain.
EIM_HANDLE_PORT (3)	The port for the EIM connection. The returned field is a 4 byte integer.
EIM_HANDLE_SECPORT (4)	Security type for this connection. The returned field is a 4 byte integer. Possible values: 0 - Non-SLL 1- Port uses SSL
EIM_HANDLE_MASTER_HOST (5)	If the EIM_HANDLE_HOST is a replica LDAP server, this value will indicate the master LDAP server.
EIM_HANDLE_MASTER_PORT (6)	If the EIM_HANDLE_HOST is a replica LDAP server, this value will indicate the port for the master LDAP server. The returned field is a 4 byte integer.
EIM_HANDLE_MASTER_SECPORT (7)	If the EIM_HANDLE_HOST is a replica LDAP server, this value will indicate the security type for the master LDAP server. The returned field is a 4 byte integer.

lengthOfEimAttribute  (Input)

The number of bytes provided by the caller for the attribute information. Minimum size required is 16 bytes.

attribute  (Output)

A pointer to the data to be returned.

The EimAttribute structure contains information about the returned data. The API will return as much data as space has been provided.

EimAttribute structure:

   typedef struct EimAttribute
   {
       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                          */
       EimListData  attribute;         /* handle attribute               */
   } EimAttribute;

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.

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_ATTR_INVAL (5)	Attribute name is not valid.
EIMERR_ATTRIB_SIZE (53)	Length of EimAttribute is not valid.
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_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. When configured for SSL we cannot retrieve the master information until a connection has been established to the configured system.

EIMERR_NOT_CONN (31)

Not connected to LDAP. Use eimConnect() API and try the request again.

ENOTSUP

Attribute type is not supported.

EIMERR_ATTR_NOTSUPP (6)

Attribute not supported.

EUNKNOWN

Unexpected exception.

EIMERR_LDAP_ERR (23)	Unexpected LDAP error. %s
EIMERR_UNKNOWN (44)	Unknown error or unknown system state.
