Consider the following typedef struct in C:

21:typedef struct source{
22: double  ds;             //ray step
23: double  rx,zx;          //source coords
24: double  rbox1, rbox2;   //the box that limits the range of the rays
25: double  freqx;          //source frequency
26:    int64_t  nThetas;        //number of launching angles
27:    double   theta1, thetaN; //first and last launching angle
28:}source_t;

I get the error:
globals.h:21: error: redefinition of 'struct source'
globals.h:28: error: conflicting types for 'source_t'
globals.h:28: note: previous declaration of 'source_t' was here

I've tried using other formats for this definition:


struct source{
...
};
typedef struct source source_t;

and


typedef struct{
...
}source_t;

Which both return the same error. Why does this happen? it looks perfectly right to me.

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
