init_com

Function init_com 

Source
pub fn init_com() -> Result<ComGuard>
Expand description

Initialize COM for the current thread in STA mode.

Returns a guard that calls CoUninitialize on drop. Keep it alive for the lifetime of your context-menu operations.

§Errors

Returns Error::ComInit if COM has already been initialized with an incompatible threading model.

§Example

let _com = win_context_menu::init_com()?;
// … use ContextMenu, ShellItems, etc. …
