// This module is designed to provide a uniform method of sending commands to
// the board through command packets. The difficulty is, some commands take
// parameters, others do not. Furthermore, it is often useful to send several
// commands to the same channel as part of the same packet. (See also i2pack.h.)
//
// This module is designed so that the caller should not be responsible for
// remembering the exact syntax of each command, or at least so that the
// compiler could check things somewhat. I'll explain as we go...
//
// First, a structure which can embody the syntax of each type of command.
//
typedef struct _cmdSyntax
{
	UCHAR length;   // Number of bytes in the command
	UCHAR flags;    // Information about the command (see below)

	// The command and its parameters, which may be of arbitrary length. Don't
	// worry yet how the parameters will be initialized; macros later take care
	// of it. Also, don't worry about the arbitrary length issue; this structure
	// is never used to allocate space (see i2cmd.c).
	UCHAR cmd[2];

#define END 4           // Set if this must be the last command in a block
#define VIP 8           // Set if this command is special in some way and really
						// should only be sent from the library-level and not
						// directly from user-level
#define VAR 0x10        // This command is of variable length!

// Declarations for the global arrays used to bear the commands and their
// arguments.
//
// Note: Since these are globals and the arguments might change, it is important
// that the library routine COPY these into buffers from whence they would be
// sent, rather than merely storing the pointers. In multi-threaded
// environments, important that the copy should obtain before any context switch
// is allowed. Also, for parameterized commands, DO NOT ISSUE THE SAME COMMAND
// MORE THAN ONCE WITH THE SAME PARAMETERS in the same call.

// Now, refer to i2cmd.c, and see the character arrays defined there. They are
// cast here to cmdSyntaxPtr.
//
// There are library functions for issuing bypass or inline commands. These
// functions take one or more arguments of the type cmdSyntaxPtr. The routine
// then can figure out how long each command is supposed to be and easily add it
// to the list.
//
// For ease of use, we define manifests which return pointers to appropriate
// cmdSyntaxPtr things. But some commands also take arguments. If a single
// argument is used, we define a macro which performs the single assignment and
// (through the expedient of a comma expression) references the appropriate
// pointer. For commands requiring several arguments, we actually define a
// function to perform the assignments.
