Detailed Description

RAII wrapper for an interface.

This type assumes the interface is already claimed at the point of construction. The destructor will attempt to release the interface and may throw if the release operation fails.

Note

Satisfies detail::DeviceHandleSource.

Constructor & Destructor Documentation

~interface()

co_usb::interface::~interface ( )

inline

Releases the interface.

Exceptions

std::system_error

if release fails.

Use release to avoid throwing.
