3.3.1 DLI Optional Arguments

Section 3.4 and Section 3.5 describe the dlWrite and dlRead functions for an FMP

application. Both functions can use the optional arguments parameter to provide the

protocol-speciﬁc information required for Raw operation (Section 3.1.2). The “C” def-

inition of the optional arguments structure is shown in Figure 3–1.

typedef struct _DLI_OPT_ARGS

{

unsigned short usFWPacketType; /* FW_CONTROL or FW_DATA */

unsigned short usFWCommand; /* FW_ICP_WRITE, FW_ICP_WRITE_EXP */

/* or FW_ICP_READ */

unsigned short usFWStatus;

unsigned short usICPClientID;

unsigned short usICPServerID;

unsigned short usICPCommand; /* Required for start/stop cmds */

short iICPStatus; /* ICP return error code (dlRead) */

unsigned short usICPParms[3];

unsigned short usProtCommand; /* Required field (dlWrite) */

short iProtModifier;

unsigned short usProtLinkID;

unsigned short usProtCircuitID; /* Used for translation tables */

unsigned short usProtSessionID;

unsigned short usProtSequence;

unsigned short usProtXParms[2];

} DLI_OPT_ARGS;
