base is being cast into an unsigned long, and the result of base & TBASE_DEFERRABLE_FLAG is being cast into an unsigned int.

Hi,
The
could be explained as follow
1. base is casted into unsigned long data type
2. the result of the case is being operation by bit operated '&'.
3. the final result is transformed to 'int' data type which is the return type of the function.
I hope this helps
