It's the first time I'm trying to use typedef. Admittedly I don't have a very clear idea of what's going on but my understanding was that the values inside typedef get assigned integers starting with 0. I've tried to use them as integers but I get various warnings and errors. One of them is "[NSCFNumber objectForKey:]: unrecognized selec...
I am trying to understand what this means, the code I am looking at has
in .h
typedef void (*MCB)();
static MCB m_process;
in .C
MCB Modes::m_process = NULL;
And sometimes when I do
m_process();
I get segmentations fault, it's probably because the memory was freed, how can I debug when it gets freed?
I hope my questions ar...
I am writing a LinkedList in C, the below code represent my Node definition.
typedef struct {
int value;
struct Node* next;
struct Node* prev;
} Node;
I understand (or think that I do) that struct Node not the same as typedef struct Node. Granted my code compiles and runs as it's supposed to, however, I get a lot of warnin...
I'm getting a compiler error on FreeBSD:
error: invalid combination of multiple type-specifiers
From the C++ Code:
typedef unsigned off_t uoff_t;
Not sure what the gcc compiler is trying to tell me.

Hello there!
I have this before the interface declaration in my MainView.h header.
typedef enum { UNKNOWN, CLEAR, NIGHT_CLEAR, CLOUDY, NIGHT_CLOUDY } Weather;
Then I declared it like this:
Weather weather;
Then made an accessor:
@property Weather weather;
And synthesized it.
My question is, how can I use this in a different...
Hello there!
I had asked a question similar to this before, but I have a new problem with it so I've reposted part of the question.
I have this before the interface declaration in my MainView.h header.
typedef enum { UNKNOWN, CLEAR, NIGHT_CLEAR, CLOUDY, NIGHT_CLOUDY } Weather;
Then I declared it (in my MainView) like this:

Is it a good idea to do the following in C++:
typedef std::map<std::string, boost::any> MyVals;
// Is the following typedef'd type inside a map a good idea?
typedef std::map<std::string, MyVals> TagValues;
These maps will be used a lot for sequential insertion and removal.
