Macro va_list::to_va_list
[−]
[src]
macro_rules! to_va_list { ($func:expr, $($args:expr),*) => { ... }; ($func:expr) => { ... }; }
This macro is the only thing provided by this crate.
Arguments
It expects a closure as first argument and then the arguments
that'll be used to build the va_list
.
Example
unsafe { to_va_list!(|v: va_list::va_list| { vprintf(b"%d %d %s %f\n\0".as_ptr() as *const c_char, v); }, 1, 2, b"salut!\0".as_ptr(), 32f32 as c_double); }
Warning
It might exist a limit to the number of arguments you can actually pass. A big one, but don't try to send thousands of them at once.
