to use a pair of parentheses following the macro name. A function-like macro’s name is only prolonged if and only if it is followed by a pair of parentheses. If we don’t do this, the function pointer will be set to the real function’s address, which will result in a syntax ...
Currently adding to pointers doesn't work: stdin:1:37-38: ERROR: The + operator can not be used on expressions of types cast, integer BEGIN { $a = (uint16*) 123; $b = $a + 5; } In C adding to a pointer uses the pointee size to increment,...

When you're using C++\CLI to define types, the this pointer in a reference type is of type handle. The this pointer in a value type is of type interior pointer.These different semantics of the this pointer can cause unexpected behavior when a default indexer is called. The next example ...

However it cannot have a variable with the same name as a function and know which one to call, so that's probably why it fails (or maybe because it's a runtime error and functions are really just pointers, it might be trying to call a function thinking thatint readis a pointer to ...
This example is confusing for me. Since addr space 0 is a union of all concrete addr spaces including 1, 2, 3, 5, etc, an actual global pointer with MD promising not alias to 0 is self-contradictory. If in this example the MD is promising not alias to 5 then it has no confusion...
