A CS_DS_OBJECT, or directory object, structure, contains information about a directory entry. Client-Library and Server-Library use a directory to store the network address information required to create connections. Storage for the directory can be provided by the Sybase interfaces file or a network-based directory, such as the Windows Registry.
An application receives pointers to one or more CS_DS_OBJECT structures as the result of a directory search by the Client-Library routine ct_ds_lookup.
