I have a couple of questions.
I need to write a program(winapi) that will create a buffer of a fixed size, then append strings to it and returns it.
1. Is it even possible for "main" to return a buffer?
2. How should I create, append string and return it?
I am not new to C, but I have very little experience with buffers and strings handling.
Thank you!

1Yes, `main` can/may return _integer_ but not _buffer_, but first of all try something to write by yourself. Read [this](http://stackoverflow.com/questions/204476/what-should-main-return-in-c-and-c). – rakeb.mazharul Jul 02 '15 at 07:48

@SouravGhosh, I was looking for some good link for OP about what `main` returns, then I will inform you about the update. Cheers! – rakeb.mazharul Jul 02 '15 at 07:57

It sounds like you either have misunderstood the problem description or the problem description is unclear. (It's common for beginners to confuse *return* and *output*, so that might be the issue.) – molbdnilo Jul 02 '15 at 08:02

No and you shouldn't. What should main() return in C and C++?
- How should I create, append string and return it?
char aString[FIXED_SIZE];
memset(aString, 0, sizeof aString);
strcpy(aString, "This is a string");
0
main in c only returns an integer, which is used to indicate the success or failure of the program.
See What should main() return in C and C++?
What you might want to consider is writing to stdout (What does it mean to write to stdout in C?) or direct to a file.
