How to call C from Swift?
...t zlib
public class Zlib {
public class func zlibCompileFlags() -> UInt {
return zlib.zlibCompileFlags()
}
}
You don't have to put the zlib library name in front, except in the above case I named the Swift class func the same as the C function, and without the qualification the...
What does a type followed by _t (underscore-t) represent?
...rs I've forgotten. The C99 standard defines a lot of extra types, such as uintptr_t, intmax_t, int8_t, uint_least16_t, uint_fast32_t, and so on. These new types are formally defined in <stdint.h> but most often you will use <inttypes.h> which (unusually for standard C headers) includes...

What is the strict aliasing rule?
...work msg) onto a buffer of the word size of your system (like a pointer to uint32_ts or uint16_ts). When you overlay a struct onto such a buffer, or a buffer onto such a struct through pointer casting you can easily violate strict aliasing rules.
So in this kind of setup, if I want to send a message...
