14/// Runs a sysfunc (syscall). All arguments are u32: argument 1 is eax, 2 is ebx, 3 is ecx, etc.
15/// Returns (u32, u32) with (eax, ebx).
16///
17///
18/// Example:
19/// ```rust
20/// fn kolibrios_exit() -> ! {
21///     unsafe {
22///         syscall!(u32::MAX);
23///         unreachable!()
24///     }
25/// }
26/// ```
27///
28/// Using returned value(s):
29/// ```rust
30/// use core::ffi::c_void;
31/// unsafe fn malloc(size: u32) -> *mut c_void {
32///
33///     let eax; 
34///     unsafe {
35///         // Sysfunc 68.12, allocate memory block
36///         eax = syscall!(68, 12, size).0
37///     }
38///     eax as *mut c_void
39/// }
