I have come across this C sample code and I have no idea what it means:
#include <stdio.h>
int some_int;
int fun (some_int) int* some_int;
{
return 0;
}
int main()
{
return 0;
}
Why is fun declared that way and what does it even mean? I can't understand the syntax.
int fun (some_int) int* some_int;
{
...
}
is the old (pre ANSI C) way to write this:
int fun (int* some_int)
{
...
}
Best you forget about this, unless you need to dig into very old source code.
If you found this in a book, throw it away and get a modern C text book. (Actually don't throw it away but keep it as an antique).
BTW the int some_int; declaration right after #include <stdio.h> is a global variable whose name is totally unrelated to the some_int in the fun function.
This SO article explains it in more details.
