Function:
int ChipKITClientPeek(TCP_SOCKET hTCP)
Description:
This routine returns the next byte in the buffer without removing it from the buffer
or -1 if no byes are available.
Precondition:
hTCP must be open and valid.
Parameters:
hTCP - The socket to check
Returns:
The number of bytes in the input buffer or -1 if no bytes are available.
Remarks:
This is to match functionality of the Arduino Client class peek method
