Hi all....
This is a bit of a fundamental question here but I think I only barely
grasp how this whole Locking and Unlocking chunks is all about, not
to mention I'm a newbie programmer. :\
I realize you need to set aside a block or "chunk" of memory before
assigning a variable any value but it's the how in some scenarios that
is messing me up... anyways... I hope this isn't too much of a C question
as it is a Palm Dev Forum question.....
My function calls to the database for a particular record. The problem is
I'm trying to unpack it to my struct (onOrder) but I'm getting a "Chunk
under-locked" error.
So, how do I lock the chunk while passing it through the function....?!?!
My function definition below...
static Err GetOrderRecord(DmOpenRef *dmReftoSync, UInt16 recordNum,
OnOrder *onOrder)
{
Err err = 0;
MemHandle myRecord = DmGetRecord(dmReftoSync, recordNum);
if(!myRecord)
err = DmGetLastErr();
else
{
UnpackOnOrder(onOrder, (PackedOnOrder *)
MemHandleLock(myRecord));
MemHandleUnlock(myRecord);
}
MemHandleUnlock(myRecord);
return err;
}
