So i saw this today from ERDAS's software SDK...
code:
#define __(a) a
What the gently caress?

I was curious because they prototype their functions like:

<type> <function name> __((<parameter list>))

It is so they can change it to #define __(a) () to support C compilers that do not implement function prototypes, I suspect.

I am confused. Isn't a prototype just a function declaration without its implementation?

It is, basically. But in C before prototypes, you would not give the parameter list when declaring functions.

Clearly degrees and radians ought to be given in separate types so that trigonometric functions can be overloaded on them.

No, it would not, it would be perfectly fine, except nobody expects to have to do that when given a const reference, or any reference at all.

My guess is that the guy is or used to be a C++ programmer (where "new" is basically malloc plus constructor).

It still never returns NULL, unless you turn off exceptions or do something crazy like that.

"Array" is not vague terminology in C, C++,

So I guess I will be okay if I dynamically allocate enough memory for N objects of type T and just have a pointer to them instead of declaring a T[N]?

# ¿ Mar 18, 2010 15:39

Vanadium: Jan 8, 2005

How is the former an array?

vvv that just means you access the elements of actual arrays through a pointer, it does not make everything you can point to an array

Yes an actual recommendation to coerce to a smaller type without an explicit cast. I know C lets you. It usually is not a good idea.

But... getchar() only ever returns values in the unsigned char range, except for when it returns EOF, so what could possibly go wrong?

Yeah, it is, if you initialise an array but do not give values for all the elements, the remaining ones get set to zero.

It would work for reasonably short strings (or if you have reasonably big integers) if you multiply each n'th character's value by 256 to the n'th power. :colbert:

They'll need a bigint class for that, they could implement it as a char array, they'll just have to implement integer comparison.

Luckily, we already have a function for that, or so goes the intuitionistic introduction to recursion.

It is when you do a syscall and the syscall is happily doing its thing and nothing is going wrong and then it suddenly returns -1 anyway because you received a signal or something dumb, and then you have to just do the same thing again and hope you do not get a syscall this time. Or a timeout, or whatever.

If they don't understand Subversion (which has an arguably easy to use Tortoise interface) then I doubt they would comprehend git/merc much less use it properly.

*"" is '\0', typeof('\0') is char, (char**) is a cast to pointer to pointer to char, and the * dereferences it so you get a pointer to char to pass to puts, which happens to point at successive elements of argv.
