Perhaps you wish to StrCopy(InBuff, strRBuff) instead?
I would not personally use StrCopy, as this will copy all characters
up until the terminating NULL, which
will not always exist after the single character you wait for.
Try an algorithm similar to this:
// bigBuf is a large buffer used to examine complete messages.
// You may receive a few bytes of a message at a time, taking
several calls to
// receive the complete message. This means you have to build the
complete message
// elsewhere, such as bigBuf. Checking bigBuf for completeness in
your case, would
// be to scan for a NUL character indicating a complete string
exists.
// Extract the string, and carry on receiving data
while (running)
{
err = SerReceiveCheck(ref, &bytesToRead)
// check err
if (bytesToRead)
{
bytesRead = SerReceive(ref, myBuf, bytesToRead, 0, &err)
// check err
if (bytesRead)
{
// append the new data onto the end of the data received
so far
MemMove(&bigBuf[bigBufSize], myBuf, bytesRead)
}
}
