Routine Description:
Convert a USHORT value to a string of bytes. Useful
for stream portability and creating WsbDbKey values.
Arguments:
pBytes - The target byte array (must at least 2 bytes long).
value - The USHORT value to convert.
pSize - Returns the number of bytes used. Can be NULL.
Return Value:
S_OK - Success
E_POINTER - pBytes was NULL.
