5.3.1 DLI Optional Arguments
Section 5.4 and Section 5.5 describe the dlWrite and dlRead functions for a
BSC 2780/3780 application. Both functions can use the optional arguments parameter
to provide the protocol-specific information required for Raw operation
(Section 5.1.2). The “C” definition of the optional arguments structure is shown in
Figure 5–1.
