Type constants are symbolic values that identify the datatype of a program variable. Many CS-Library, Client-Library, and Server-Library routines take the address of a program variable as a CS_VOID * parameter. Type constants are required to identify the datatype when passing CS_VOID * parameters. Typically, a type constant is passed to a routine as the datatype field of a CS_DATAFMT structure. (See “CS_DATAFMT”.)
