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...
How do I shuffle an array in Swift?

Hidden features of C

int8_t
int16_t
int32_t
uint8_t
uint16_t
uint32_t
These are an optional item in the standard, but it must be a hidden feature, because people are constantly redefining them. One code base I've worked on (and still do, for now) has multiple redefi...
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...
