/* # main function

*

* ## Call main from the program

*

* Seems legal:

* http://stackoverflow.com/questions/13948562/recursion-using-main-function#comment19237980_13948579

*

* Illegal in C++ however.

*

* ## main signature

*

* - http://stackoverflow.com/questions/204476/what-should-main-return-in-c-and-c

* - http://stackoverflow.com/questions/4207134/what-is-the-proper-declaration-of-main

*

* Valid signatures: either:

*

* int main(void)

*

* or:

*

* int main(int argc, char *argv[])

*

* Or equivalent ones to the above:

*

* argc array vs pointer: (TODO why equivalent)

*

* int main(int argc, char **argv)

*

* Default return type `int` (C89 only):

*

* main()

*

* Explicit `void` prototype:

*

* int main(void)

*

* ## main return

*

* Valid returns are:

*

* - `EXIT_SUCCESS` or `0` to indicate success

* - `EXIT_FAILURE` to indicate failure

*

* C99: return is optional. If omited a `return 0` is added to the program.

*

* But just always return to be C89 compatible.

* TODO I think that in C89 it is legal to not use return like for any other function,

* but it leads to UB.
