Would someone be kind enough to explain this line of code:
int main (int argc, const char * argv[])
I can find no reference to "argc" or "const" or "argv", and I do not
understand the use of the () at all.
The best I can guess at is that the variable "main" is an integer that
could be either "argc" or the product of "const" times "argv[]".
Damn, I hate having to ask these dumb ass questions. Thanks again,
Apple.
This has nothing at all to do with Apple documentation issues.
This is basic C stuff
main is a function that returns an integer value
argc is an integer that holds the count of the number of items in
the argv array
finally, the argv[[] is an array of const char * that has as many
elements as the argc says.
This is the prototypical unix main. the command line parameters
are contained in the argv[]. Even if you're using Cocoa apps, this will
be the standard main.
As others have said, this is basic C stuff. There are loads of C
books out there, and many are crap.. assuming that it might be good book
based on the fact that it's written by a PhD is just a bad idea. I
wouldn't even attempt to say that 'x' is a good book on the topic. I'd
go to Amazon or FatBrain and browse and read the user comments.
BTW: I know that we all started at the same place, and that questions
have to be asked (and answered) in order to learn. However, the
accusatory and snippy tone that is prevalent in your particular
questions (which always contain commentary) is a bit tiring. This is
not an issue of poor documentation on Apple's part.
