Following code is giving Bus Error at bmp create (last
line). Any idea.
I am using SDK 3.5 and GNU gcc for compiling
application. Using Emulator for testing with release
ROM ( Palm OS 3.5-en-color.rom ) . Also I have
install newest PilRC.
With Code warrior this piece is perfectly fine.
Thanx,
Nimesh.
==============
static BitmapPtr GetSigBitmap( RectangleType*
theBoundsPtr )
{
WinHandle theWindowHandle ;
Word theError ;
BitmapPtr theBitmapPtr ;
Word theRowBytes, theHeight ;
UInt32 romVersion ;
UInt32 size = 0 ;
UInt16 width, height ;
WindowType *winP ;
Err *errorP ;
UInt32 sizeP = 0 ;
UInt16 rowBytes ;
UInt8 depth ;
// First, free the previous bitmap if it exists
if (gBitmapPtr)
{
MemPtrFree( gBitmapPtr );
gBitmapPtr = NULL;
}
theWindowHandle = WinCreateOffscreenWindow(
theBoundsPtr->extent.x,
theBoundsPtr->extent.y,
genericFormat,
&theError );
if (!theError)
{
FtrGet(sysFtrCreator, sysFtrNumROMVersion,
&romVersion);
if (romVersion >= version3_5)
{
RGBColorType rgb = {0,0,0,0};
drawIndex = WinRGBToIndex(&rgb);
newAPI = true;
}
// Now, copy the gadgets screen rectangle into the
new window. This will offset
// the screen bits to (0, 0) in the offscreen
window.
WinCopyRectangle( NULL, theWindowHandle,
theBoundsPtr, 0, 0, 0 );
if (newAPI)
{
BitmapPtr winBmpP = WinGetBitmap(theWindowHandle);
ColorTableType *clrTableP =
BmpGetColortable(winBmpP);
UInt8 depth = winBmpP->pixelSize;
WinHandle winH;
// we create a bitmap and then make a window to it
so that we can
// create a bitmap whose depth does not match that
of the screen
theBitmapPtr = BmpCreate(theBoundsPtr->extent.x,
theBoundsPtr->extent.y, depth, clrTableP, errorP);
