33// This module is designed to provide a uniform method of sending commands to
34// the board through command packets. The difficulty is, some commands take
35// parameters, others do not. Furthermore, it is often useful to send several
36// commands to the same channel as part of the same packet. (See also i2pack.h.)
37//
38// This module is designed so that the caller should not be responsible for
39// remembering the exact syntax of each command, or at least so that the
40// compiler could check things somewhat. I'll explain as we go...
41//
42// First, a structure which can embody the syntax of each type of command.
43//
44typedef struct _cmdSyntax
45{
46 UCHAR length; // Number of bytes in the command
47 UCHAR flags; // Information about the command (see below)
48
49 // The command and its parameters, which may be of arbitrary length. Don't
50 // worry yet how the parameters will be initialized; macros later take care
51 // of it. Also, don't worry about the arbitrary length issue; this structure
52 // is never used to allocate space (see i2cmd.c).
53 UCHAR cmd[2];
54} cmdSyntax, *cmdSyntaxPtr;
55
56// Bit assignments for flags
57
58#define INL 1 // Set if suitable for inline commands
59#define BYP 2 // Set if suitable for bypass commands
60#define BTH (INL|BYP) // suitable for either!
61#define END 4 // Set if this must be the last command in a block
62#define VIP 8 // Set if this command is special in some way and really
63 // should only be sent from the library-level and not
64 // directly from user-level
65#define VAR 0x10 // This command is of variable length!
66
67// Declarations for the global arrays used to bear the commands and their
68// arguments.
69//
70// Note: Since these are globals and the arguments might change, it is important
71// that the library routine COPY these into buffers from whence they would be
72// sent, rather than merely storing the pointers. In multi-threaded
73// environments, important that the copy should obtain before any context switch
74// is allowed. Also, for parameterized commands, DO NOT ISSUE THE SAME COMMAND
75// MORE THAN ONCE WITH THE SAME PARAMETERS in the same call.

170//

174// (through the expedient of a comma expression) references the appropriate
175// pointer. For commands requiring several arguments, we actually define a
