-
-        Functional description:
-          Reads 32 bits from stream and returns the bits, does not update
-          stream pointers. If there are not enough bits in data buffer it
-          reads the rest of the data buffer bits and fills the lsb of return
-          value with zero bits.
-
-          Note! This function will skip the byte valued 0x00 if the previous
-          byte value was 0xFF!!!
-
-        Inputs:
-          StreamStorage *pStream   Pointer to structure
-
-        Outputs:
-          Returns  32 bit value
