Hey folks,
I desperately need a little debugging help.
Can anyone tell me why this would bomb (Fatal Exception)? Here's the
struct and then the code fragment...
struct tDocRecord0 {
byte crap; // because of some flaw in some docs.
byte wVersion; // 1=plain text, 2=compressed
WORD wSpare;
DWORD dwStoryLen; // in bytes, when decompressed
WORD wNumRecs; // text records only; =tDocHeader.wNumRecs-1
WORD wRecSize; // usually 0x1000
DWORD dwSpare2;
};
Boolean SaveEBook(UInt16 cardNo, char *Filename, UInt32 length)
{
VoidHand RecHandle;
Ptr RecPointer;
struct tDocRecord0 *theRec;
Err theErr;
LocalID db;
theErr = DmCreateDatabase(cardNo, Filename, 'REAd', 'Deep',
false);
if (theErr == errNone) {
if (db) zDB = DmOpenDatabase(cardNo, db, dmModeReadWrite);
else {
FrmCustomAlert(DebugAlert, "Couldn't find db!",0, 0);
return(false);
}
if (zDB == NULL) return(false);
theRec->wVersion = (byte) 1
theRec->dwStoryLen = length; // <= Bombs here.
theRec->wNumRecs = (WORD) 2;
theRec->wRecSize = (WORD) 4096;
theRec->crap = (byte) 0;
theRec->wSpare = (WORD)0;
theRec->dwSpare2 = (DWORD)0;
...
It is bombing right at the "theRec->dwStoryLen = length;" moment.
I've tried casting it as "theRec->dwStoryLen = (DWORD) length;" as
well. Both Fatal Exception on me if the length is greater than 1000
(1024?) or so. (Well, I've seen it succeed at 600, 800 or so, and
then explode every time at 1400 or so.) I keep thinking there must be
something else going on, but my debugging attempts so far only narrow
down to this point! Am I doing something stupid??? (I must be, but
dang if I can figure it out.)
This one bug is driving me insane! Aaaaaagggg--kkk!
Thanks in advance,
zane
