Allocate the memory instead. ie,
// Allocate the buffer
fSerRcvQueue = MemPtrNew(myMinSerRcvBufSize);
if (fSerRcvQueue == 0)
err = memErrNotEnoughSpace;
if (err) goto out;
// Use our own buffer
err = SerSetReceiveBuffer(
fSerLibRefNum, fSerRcvQueue, MemPtrSize(fSerRcvQueue));
if (err) goto out;
When you close down, make sure you pass that same pointer back in, ie..
// Set the receive buffer back the way we found it
if (fSerRcvQueue) {
// Restore the Serial Manager's default receive queue
err = SerSetReceiveBuffer(fSerLibRefNum, fSerRcvQueue, 0);
// Free the buffer we created
err = MemPtrFree(fSerRcvQueue);
fSerRcvQueue = 0;
}
