this means
Expand|Select|Wrap|Line Numbers
  1. unsigned int nFlags = LOCAL | FOREIGN
in C you can omit the int, it is initialised with the value LOCAL | FOREIGN where | is the bitwise OR operator

If I take a wild guess, it looks like two 16 bit flags are being packed into a 32 bit unsigned integer.
