Detailed Description

An object interface.

Field Documentation

dest

struct interface* interface::dest

Destination object interface.

When the containing object invokes an operation on this interface, it will be executed by the destination object.

This pointer may never be NULL. When the interface is unplugged, it should point to the null interface.

Definition at line 133 of file interface.h.

refcnt

struct refcnt* interface::refcnt

Reference counter.

If this interface is not part of a reference-counted object then this field is NULL.

Definition at line 139 of file interface.h.

Referenced by intf_get(), intf_init(), and intf_put().

desc

struct interface_descriptor* interface::desc

Interface descriptor.

Original interface descriptor.

If this is a temporary outbound-only interface created by intf_temp_init() then this field is NULL.

Used by intf_reinit().

Definition at line 145 of file interface.h.

intf

struct interface* interface::intf

Original interface.

Used for temporary outbound-only interfaces created by intf_temp_init().
