My conduit is in java and my handheld program is in C. I have had no
problems reading packed records which contain strings but integers are all
zero when I fetch them. I am wondering if my unpack routine hasa problem? I
can't see one though. My handheld C code looks like:
static void UnpackRange(RangePtr range, const PackedRange
*packedRange)
{
const char *s = packedRange->name;
itemRange->name = s;
s += StrLen(s) + 1;
packedRange->startRange = (Int32)*s;
s = s + 4;
packedRange->endRange = (Int32)*s;
//I read the name fine but StartRange and endRange are always
//zero when I unpack them this way though I know I am
//writing legitimate numbers on the java side.
}
The Range structures are:
typedef struct Range {
const char *name;
Int32 startRange;
Int32 endRange;
} Range;
typedef struct PackedRange {
const char name[1];
} PackedRange;
on the java side in the conduit I do:
public void readData(java.io.DataInputStream in)
throws java.io.IOException
{
itemRangeName = AbstractRecord.readCString(in);
startRange = in.readInt();
endRange = in.readInt();
}
public void writeData(java.io.DataOutputStream out)
throws java.io.IOException
{
if (itemRangeName == null)
itemRangeName = "";
AbstractRecord.writeCString(out,itemRangeName.trim());
out.writeInt(startRange);
out.writeInt(endRange);
}
