Hello all,
I was wondering if I might humbly ask the assistance of the combined
Knowledge of the Net in a programming problem upon which I have dwelt for
a number of evenings.
I am using Lattice 5.0. (Not completely ANSI compliant, so I have made
alterations from the code found in the 1.3RKM to make it K&R compatible.)
What I would like to do is take IntuiMessage RAWKEY events and feed them into
the routine DeadKeyConvert() found on page 197 of the 1.3RKM. and have it
return an ASCII sequence back in the form of a character if a character key
was stuck, or a couple characters representing a cursor key, function key,
etc. As far as I can tell it is not returning anything. If anyone can point
out my errors, I would appreciate it.
The program returns rawkey events correctly as can be seen from
the output. It just seems that the DeadKeyConvert() routine does not seem
to touch the string pointed to by *buffer.

/* Declare and initialize the NewWindow structure: */

struct IOStdReq ioreq;

struct IntuiMessage *msg;
char *kbuffer;
LONG kbsize;

{
static struct InputEvent ievent={NULL, IECLASS_RAWKEY,0,0,0};
if (msg->Class !=RAWKEY)
return(-2);
ievent.ie_Code=msg->Qualifier;
ievent.ie_position.ie_addr=*((APTR*)msg->IAddress);
return(RawKeyConvert(&ievent,kbuffer,kbsize,kmap));
}
/********************************************************/
void main() /* This segment is just to show variables defined/used */
{
/* Boolean variable used for the while loop: */
BOOL close_me;
ULONG class; /* IDCMP flag. */
USHORT code; /* Code. */
USHORT Qualifier; /* Qualifier */
char *buffer="This is the string to end all strings "; /* To hold ASCII code representations */
LONG count; /* Length of key string returned by DeadKeyConvert */
/***** Necessary for RawKeyConvert ***/
/**/
/**/ if (OpenDevice("console.device",-1L,(struct IORequest *)&ioreq, 0L))
/**/ printf("Could not open the Console.device");
/**/
/**/ ConsoleDevice=(struct ConsoleDevice *)ioreq.io_Device;
/**/
/****************************************************************/
case RAWKEY: /* A RAWKEY message has arrived! */
printf("%d =Qualifier \n",Qualifier);
printf("%d =Code\n",code);
count=DeadKeyConvert(my_message,(UBYTE *)buffer,10,0L);
printf("%s =string\n",buffer);
printf("The count is %d\n",count);
break;
The program reaches the case statement and prints the following while I strike
the keyboard:
32768 =Qualifier
32 =Code
This is the string to end all strings =string
The count is 0
...
...
I apologize for the length of this post, but I wanted to be as complete as
necessary. Thank you for your assistance and have a good day.
