The Client-Library header files define OID strings for applications to use in initializing or comparing OIDs. Predefined OID strings are used for the following purposes:
Identifying directory object. Sybase directory object is Server, and the OID is CS_OID_OBJSERVER.
For more information, see “Server directory object”
Identifying the attributes of a given directory object. See the definition of the directory object for the predefined OID strings that identify each attribute.
