struct struct0 {
  int a;
};

struct struct1 {
  struct struct0 structure0;
  int b;
} rho;


&rho->structure0; /* Reference 1 */
(struct struct0 *)rho; /* Reference 2 */
(struct struct0)rho; /* Reference 3 */

From reference 1, does the compiler take the address of rho, and then access structure0, or vice-versa?
What does the line at reference 2 do?
Since structure0 is the first member of struct1, would reference 3 be equivalent to reference 1?

The definition of AudioBufferList looks weird to me… i guess my C is not so good struct AudioBufferList { UInt32 mNumberBuffers; AudioBuffer mBuffers[kVariableLengthArray]; }; typedef struct AudioBufferList AudioBufferList; Why AudioBuffer mBuffers[kVariableLengthArray]; and not AudioBuffer… >>> More

I read about unions the other day( today ) and tried the sample functions that came with them. Easy enough, but the result was clear and utter garbage. The first example is: union Test { int Int; struct { char byte1; char byte2; char byte3; char byte4; … >>> More

Hi I am trying to use C to implement a simple struct: 2 boxes, each contains different number of particles; the exact number of particles are passed in main(). I wrote the following code: typedef struct Particle{ float x; float y; float vx; float vy; }Particle; typedef struct Box{ … >>> More
