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 //
44 typedef 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.
