We know that by convention, but how do we know that from

    pub fn main() !void {
If if write

    pub fn foo() !void {
will that function also get to return a u8?

Also, what happened to argv/argc?

No, the main function (the entry point of the entire program) is special cased. Have a look at the source code. There you can see it's calling the user defined main function and handling its return value / error.

You can access argv with std.os.argv which is a slice of null terminated strings. It's better to go with std.process.argsAlloc though (requires an allocation but works on all supported platforms).
