strict_context_handle attribute
The [strict_context_handle] ACF attribute sets restrictions on context handles.
[
strict_context_handle
[, interface-attribute-list]
]
interface interface-name
{
interface-definition-statements
}
Parameters
-
interface-attribute-list
-
Other ACF attributes that apply to the interface as a whole. Valid attributes include auto_handle, implicit_handle, explicit_handle, and optimize, code, or nocode. Separate multiple attributes with commas.
-
interface-name
-
The name of the interface.
-
interface-definition-statements
-
One or more MIDL statements that define the elements of the interface.
Remarks
Normally, when a call to an interface method generates a context handle, that handle becomes freely available to any other interface. When you use the [strict_context_handle] attribute you guarantee that the methods in that interface will only accept context handles that were created by a method from the same interface. Interfaces compiled without [strict_context_handle] cannot accept context handles created on interfaces compiled with [strict_context_handle].
